    2006 Q7 - Torque up by 27% drives like a different car! highly recommend these guys. Might be pricey but compared to the value of the vehicle well worth it.

    These fellas dida killer job on my Hilux. It was previously chipped and their tune just blew it out of the water. More power, more torque and better fuel economy. Also better value for money.

    In love with my ute even more now.

    Cheers guys!

    Had my NP300 fitted and tuned with a Unichip by the guys in Dandenong a few weeks ago. Over 30% gain in power and torque right where it's needed, with a neat install I couldn't be happier with the results both drive-ability, performance and overall decrease in fuel consumption. Sales staff are professional, and always help with answering questions over the phone and online. I wouldn't hesitate to recommend UDT. Thanks again guys.

    I was very impressed with the job done on my 2012 Colorado. Lots more power and torque and before the tune fuel economy was 8.1 L per 100km and now it is 6.8L per 100km. Great service and people. I can't recommend them highly enough.

    I rolled up last week after limping around in my 2014 MN Triton for the last two months with manifolds clogged to the gills with carbon in only 35,000km. Dealer didn't want to know about it as it's a known issue with Triton EGR's. Had already decided at the same time of doing the desoot to get an exhaust, catch can, secondary diesel filter, tune and K&N air filter. They all pair up to each other extremely well and the HPD products that ultimate stock along with the legendex exhausts are simply a fantastic piece of gear.

    Turned up on Thursday not expecting to have the car back till Tuesday and sure enough the boys had it finished by Friday and I grabbed it Monday morning. Goes like the absolutely bloody clappers now. Can't stop smiling and leaving everyone behind in a cloud of diesel Smoke, boy racers look out.

    Cheers for the hard work fellas and can't wait to come back for the rest of the toys

    l was nervous about the tune and what it entailed. the guys talked me through what was going to happen. I was surprised at how silly the question it was answered as if it most important. I don't know much about diesel and I was surprised at how much the tune improved the performance and economy. I would recommend ultimate diesel tuning for their friendly service and their dedication to doing a great job

    Thanks to the boys at geebung store for the 3" exhaust and the custom tune done on Friday certainly did notice the extra power and torque over the weekend up at Bribie island and looking for to the extra fuel economy

    Just had my VDJ76 Landcruiser in for a de-soot, exhaust, crossover pipe, clutch and a tune. Car came back totally different! Way more response, sounds great, better on fuel and much more pleasant to drive, especially when loaded up to go touring or towing my trailer for work.

    Customer service was great, was given a loan car to tow my trailer to work and my car was back to me in 3 days.

    Would definitely recomend!
