Torque is the ability to transform engine power in wheel motion and so in “pull force”. More Torque means more efficiency.

Diesel engine performs more Torque at low engine’s revs. Petrol engine performs more Torque at higher engine’s revs.

A vehicle with more Torque needs less open throttle to maintain the same speed at the same condition, resulting in

– less fuel burned,

– a more responsive vehicle,

– a safety enhanced vehicle.

With more Torque and more Power, differences are noticeable. At the first ride.

We increase Power and Torque in a safe spot.

Our Dyno Custom Tuning provide an average of extra %20 of Power at the wheels.

We unleash the real power of your Diesel engine within manufactory’s limits.

This is a typical Dyno test before/after:

To see what are the gains for your vehicle just hit our search bar here.

If more torque gives that less throttle is needed to maintain same cruising speed, it means that less fuel is needed.

With our ECU Remap you will save between 10% to 20% in fuel consumption.

See your vehicle in detail (here).

A common question is: how safe is your tune?

Our best answer is:

A” diesel tuner” is like a “doctor for cars”.

Your car is not feeling good and you bring it to a tuner.

Same we humans do when not feeling good, we go to a doctor.

What makes a doctor “safe“?

Picking some:

  • Experience (Usually the longer the better)
  • Special diagnostics tools (Top level equipment is a plus for every doctor)
  • Facilities (A State-of-the-art facility can help a doctor a lot)
  • Teamwork (Many experiences combined are better than a single)
  • References (What happen to previous “customers” is something better know).

A Diesel Tuning is considered “safe” when all of above are at their best.



  • For my beloved 2014 Toyota landcruiser Prado, Gary has tuned my car twice now. First tune 3 years with a stock engine gave great fuel economy and power increase. Now that I’ve significantly changed the intake and exhaust the second stage tune has also delivered a great result with the engine running safely reflected in coolant temperatures and EGT’s. They are professional, knowledgeable and really seeked to understand what I use my vehicle for and on each tune I have had no issues with my vehicle. Highly recommended and I wouldn’t take my vehicles anywhere else. A big thank you to Gary and his team

    My 4cyl twin turbo tdi420 Amarok was constantly going into limp mode due to a DPF issue. I spoke to the diesel experts at DTA who said they could fix the problem. While the car was in there I also got a tune. They took my Amarok from 420nm at the flywheel to almost 650nm at the wheels! Mind you I did have a few other small mods, mostly to help the breathing… 3 inch stainless exhaust from turbo K&N filter safari snorkel Fat cold air pipe from air filter box to turbo They completely changed my car. Highly recommended.

    Brought my ford ranger in for a tune + EGR delete as I was getting stupid high fuel economy. Brought the ranger in, the boys located a faulty exhaust sensor and managed to have one delivered by ford same day, installed then completed the dyno and all. Cars running a hell of a lot better now and stoked with the fuel economy aspect of things. 110% recommend. Local, same day turn around job. Cheers!

    Took my ranger in for a tune and after I found it had an injector cost when cold. Thanks too Gary and his team they worked tirelessly through what the issue could have been and found the problem plus giving me an awesome tune. It looked like I might of needed to change the injectors but luckily Gary found a problem from a previous tune that had changed parameters that should never be changed.

    We’ve had 2 SUV’s tuned here and have been very happy. My 2011 Touareg is a totally different car! Getting consistent 6.5L/100 on highway runs and it has mountains of torque and responsiveness down low which it never had. 100Nm more at peak but literally double down low where you actually use it! Absolutely love it. Will be coming back when I get the next one.

    I want to thank the team at DTA for the great work they did on my 2022 Amarok. The remap tune made my vehicle come to life. Very professional. These guys are the real deal. The tune was individual to my needs. Highly recommend DTA at Mascot. Craig

    2014 Nissan patrol. Very slow to obtain any speed and heavy on fuel even when just driving around the place. (Then put the camper on it and up goes the fuel rate). Then made the decision to have a re map, but by who as everyone tells a different story. I did my own homework and found the company DTA Diesel Tune kept being mentioned. I had already fitted a 3in exhaust system which did help the way the vehicle drove. Made a booking over the net which was very easy to do and even had a reply in no time. Drove to the workshop of DTA and meet up with the owner Gary. The shop was full of all sorts of vehicles. They took the vehicle around the back and started work on it. Gary returned and advised they were unable to do any further work as a part was unable to be supplied and fitted. Asked about just checking the vehicle on the dyno just in case something else needed to be done. Gary carried the dyno out and advised it was well down on power. I said the lights had to be turned off, so it does not see the hills coming. (Ha Ha) was the comment. 01-12-2022 The next time after the parts were obtained all went well and a full re map and dyno testing was carried out. The test results showed an increase from 85Hp to 109 Hp and an increase in torque as well from 319Nm to 416Nm. In driving the Nissan home, it felt a different vehicle. The patrol was not used until we went away for the big break over Xmas and the new year. Loaded up (not towing) with all my tools etc for this trip. Heading south to Eden I could feel the different capability in the way the power was coming on as we could overtake other cars without much trouble, and the throttle was not even pushed to the floor as before. In the comment above as turning the lights off I can now even leave the lights on and use the aircon plus overtake cars pulling up many hills. As for the fuel usage this has improved as I can return from Eden and still have over ¼ tank left. The towing of the camper I feel will also have improved as it is totally a different vehicle. Thanks to Gary and his team. Well, done.

    Recently had my MY20 Grand Cherokee tuned by Gary and am really impressed with the results! There was a nasty dip in both power and torque at low rpm in the stock tune which accounted for the really poor response, now power delivery is instant and smooth. The team at DTA/Hi-Tech kept me informed of progress while they were working on it and were very honest and easy to deal with. Great service and end result, thanks!!

    I need to share my experience with those who are considering having automotive work done by Diesel Tuning Australia. My reviews are few and far between but these guys deserve a mention. Firstly, I took my car to Audi for some warranty mechanical work. Can I just say, the experience with a large brand (Audi) workshop was far from what you'd expect. I was disappointed with the service and customer hand off. My ecu tune was compromised and the car felt lethargic. I called DTA and spoke with the wonderful people over the phone and my car was booked for a tune upgrade. Gary, the business owner greeted me personally in both instances, at drop-off and pickup. My Audi A5 3.0TDI was in need of a tune upgrade. Gary explained the whole process to me from start to finish. I'm amazed that he can find the time to personally tend to his customers, as he runs an extremely busy workshop. This guy has the winning formula. He invests in his customers and builds on his relationships, unlike most others in the automotive industry. I can see exactly why his business has gone from strength to strength. Well done to Gary and his team. I will be returning with my Audi A4 2.0 TFSI for an upgrade also. By the way, I opted in for the DSG tune at the same time and I have to say "Wow!". It's a completely different beast now. *****5 STARS ***** from me. Steve

    I recently had my landrover defender tuned/remapped at DTA which I gained a massive power increase the Rover went from being okay to drive due to being sluggish being such a heavy vehicle with a small engine to extremely enjoyable to drive and powerful thanks to Garry and the team. Super professional encounter and I really appreciate the personal level of interaction they give rather than just another customer they have to deal with speaking from a customer facing background 10/10 recommendation couldn't be happier thanks Garry and the Team

    I had my 2018 wildtrak px2 Ranger tuned by Gary. I Dropped in early on Monday morning.. I Had it back by lunch same day. I honestly think I picked up a different Ranger. It's responsiveness and outright pull really impressed me immediately. I live out in the central west so driving up the Blue mountains on the highway used to be a automatic gear change nightmare with Ranger looking for more gears to climb... Well not anymore.. it now climbs effortlessly.. checking the litres per klm now using best of 2 litres per 100 klm less.. Thanks

    Gary and his team are the most genuine and most professional mechanics I've come across. Did an awesome job on my cruiser. Turned it into a beast. Also cleaned out the manifold which was completely caked and made it look brand new. They are an A grade mechanic that I will always trust my family's vehicles with.

    I took my NP300 in on a Monday morning as it was in limp mode. Although I wasn't booked in and they were busy, Gary said he would fit me in anyway. Gary took the time to talk me through everything that was done to my car. Very happy with the entire team at Diesel Tuning Australia and Hitech Automotive. Customer service like this is very rare these days, and very much appreciated. Highly recommended business

    I’ve owned my 2012 V6 Navara since new but had it re-mapped by Gary 3 years ago ….I wish I’d done it sooner as I’m more than satisfied by the increased performance and much better fuel economy he’s been able to achieve……it’s such a great work car. I’ve put 50,000 kms on the car since then but recently it stared developing an intermittent fault and would occasionally go into “limp mode” …a frustrating problem that my local service mechanic was unable to fix. Gary however was quick to diagnose and fix the problem…it turned out to be an issue with the deterioration of the foam lining the air intake & totally unrelated to his previous work. Gary gave his time and expertise to get me back on the road very willingly & without charge!!! He’s definitely someone I’d recommend if you’re looking for a true professional to get the best from your diesel.

    Took my Colorado to Gary, he found the problem, helped me order replacement parts and then fit them, all whilst talking me through every step. He then tuned it and was so helpful. Ute have such a nicer drive now. 100% chance of me returning when I need to and recommending my friends
    00:34 20 Nov 21
    A big thank you to the boys at DTA for the amazing work done on my vehicle. Not only they looked after me with pricing. The tune was better then I expected. Highly recommend guys. Gary went out of his way with the team to make things happen. Thank you so so much.

    00:04 15 Oct 21
    Gary did a tune on my 2015 Toyota Hilux it was absolutely amazing and the car performance was exceptional on and off road. The service and advice Gary gives is next level he knows his stuff inside and out and does everything to perfection. I have been here twice now and is definitely the best in the business hands down

    After having a bad experience in the past with tune on my BMW 335i I never had thought I would do another tune again. I had done my research with DTA & especially Garry and his team & the fact that Garry & his team are the first to do tuning on Diesel engines in Australia i decided to give it a go, so far all I can say is, wow, I really have to get use to the new drive on my car as it just performs much nicer, stronger & feels healthier & smoother. Most importantly the fact that the people care and listen to you and make sure all your questions are answered even though they are extremely busy which makes me feel like they care & the lovely receptionist still gave me the time to talk to Garry & go through the process with me as I was a bit nervous Thank you very much for your work Garry & looking forward to bring in my car to you guys. Thanks to the receptionist for answering my questions & proving me all information

    Just had my 2009 Navara d40 tuned at DTA. Throtle response from take off especially on steeper inclines is noticeably better. Definitely less pedal on general driving too. Can’t say for fuel economy as yet but hopefully that will improve from the factory setting. Thanks to Gary and his team.

    Diesel Tuning Australia (DTA) epitomise what customer service should be. When you arrive, the staff are quick to acknowledge you and serve you. They are welcoming, friendly and want to help you. You are kept in the loop and given the help you need efficiently. When I investigated diesel tuning services, DTA jumped out at me. I had some family have their cars serviced and tuned there, a VW Passat and a Mazda BT50. They were very impressed with all aspects of the service, from the whole customer experience to the transformation of the vehicles. The increase in performance, fuel efficiency and drivability, far exceeded expectations. My VW Amarok went in for a tune, and just like my family, the results had me grinning from ear to ear. I’d fitted an aftermarket turbo-back exhaust system and done some intake mods prior to tuning, which caused some complications in the tuning process. It was a vehicle software issue, but DTA used their talents, worked hard and got to the bottom of it. Now my vehicle has a safe, reliable, but excellent tune that has made driving an easy, fun and stress-free experience. DTA set the standards high. Their business is thriving, and the reasons why are obvious. They ensure that you leave a happy customer and they deserve all the success they get.

    Gary has tuned both my e46 m3 and my brand new Hyundai i30sr which nobody else would even dare to touch. Both cars have received massive power gains and behave like completely different cars. I strongly recommend coming here for a tune as I have had my e46 m3 tuned by Gary for 3 years now with no issues.

    11:26 08 Oct 18
    I waited 1 month before writing this review to give myself some time to see if the gains were only a placebo effect. Unfortunately it wasn't a placebo effect! The gains I got from the custom tune was in fact real and was here to stay. 90nm of extra torque made red light getaways a real Rush! No issues with the engine either. Thanks for working on my car Gary, and thanks for not charging me for the extra work that was required as well! BMW E90 320d

AdBlue is a liquid-like material used to clean exhausting gases going in the atmosphere, the same functionality of the EGR valve and in many cases this system can stop working properly causing engine’s faults.

If your AdBlue system is facing issues, please get in touch with us today to avoid expensive repairs.

We are specialised in AdBlue repairs and AdBlue delete (off-road only) via ECU.


Our goal is to increase vehicle performances and efficiency and the first important step is to diagnose the vehicle. A modern diesel vehicle is a perfect balance of electrical and mechanical parts, a small malfunction could easily lead to loss of power, black smoke, engine/turbo blowups, etc..

We bring your vehicle inside our Dyno room where few highly experienced technicians starts to inspect your vehicle.



  • – under the bonnet – (pipes, oil leaks, etc..)
  • – wheels and suspensions – (will effect Dyno readings)
  • – exhaust system,
  • – intake system (could be clogged by carbon residue).



Once our visual inspection is passed, we scan your vehicle’s computer to make sure no other issues are in place with your vehicle.

If we spot any issue we are able to address it and solve it.

This stage is crucial for a tuning to be considered as “safe”.

Once your vehicle has been inspected we perform a Dyno test to check how the engine performs.

Here we can see if performances are close to what is should be.

After the Dyno test we are ready to pull the file out of your ECU.

This can be done in 2 ways:

  •  – Remove it from the car, open it and access to file system on the bench.


  •  – Download from ODBII Port. Eventually with a Bluetooth connection.


Of course the OBDII Port is the best way as no traces will be left behind.

Where possible we use OBDII Port connections

Once we unlock your ECU files we can access to several maps (Rules) and make adjustment in order to get more efficiency, power and torque.

At this stage we can make changes in order to stop the EGR valve.

“Remember to check how your vehicle performs with our tune [here]”

Once all maps are modified, we lock the file and send it back to the ECU, saving a copy of the original file.

At this stage we test improvements on the dyno and valutate if keep this tune or adjust parameters.

Once our tuner is happy with the results he lock the new ECU file, let the vehicle cool down.

After 30 min we perform the last sequence of runs on dyno. Here we attest the new vehicle performances.

We are pretty confident that our tune is one of the most reliable in Australia.
