    If you need to get reliable power and towing capabilities out of your RC Colorado, I definitely recommend going to UDT, I went to the team at Geebung and the blokes there hooked me up and the Rado feels a lot better, especially the driving experience!

    Cheers boys 🙂

    The car performed as well as I was told it would, was ready on time and I was treated in a professional manner.

    Highly recommended the guys at UDT Geebung rob and the team worked wonders on our 2011 ford territory way better torque transfer which made gear shifts a lot smoother they basically removed the turbo lag so over taking is a breeze now and the fuel economy blew my mind I did a test on the way there reset the trip computer and avg fuel economy was 8.9 L/100km after the team worked there magic on the drive home the same route which was a 1.5hrs drive the car only slipped away at 6.6L/100km could be believe it I was hoping to see a little saving like low 8s or high 7s but mid 6s is amazing can’t wait to hook the camper up see how the towing difference is thanks guys couldn’t have asked for a better result.

    Gold Coast shop- I had the ‘chemical soot clean’ done to my LC200 due to having 200,000 km. I only had the budget to do this process or a tune. I opted for the clean for engine longevity that they claim, and due to claiming better fuel economy and power.

    Unfortunately no change in power or fuel economy whatsoever.

    Good friendly customer service though. But a lot of $$ for unseen results. I think if UDT claim better fuel economy and power from their soot clean method I think they should back it up by showing you the specs before and after which they don’t.

    My 2017 Ranger has 70,000 kms on the clock and wasn’t running as smooth as it had been.
    The guys from UDT gave the engine and manifold a good clean, fitted a catch can and did a UDT tune.
    They were clear and concise about what they were doing, it’s benefits and the cost.
    While it was there, they fitted bigger wheels, tyres and guard flares. They even had a small dent removed that I didn’t know was there!
    The car now runs so much smoother, it has zero hesitation on acceleration and flies up hills. It’s just overall much better.
    Thanks Rob and the UDT boys.

    I had my 08 Jeep jku wrangler tuned and pre fuel filter and catch can installed by the Arundel workshop.

    They went above and beyond to get every request I asked of them into my Jeep and at the quoted price and after the tune my heavy Jeep with 250k km feels like a completely new car I was astonished!!

    I handed my brand new 2019 Wildtrack over to UDT for some aesthetic upgrades. Prompt service and replies from the team regarding the changes i wanted. Couldn't be happy with the end result.

    2010 Ford Ranger tuned, desoot and intercooler done a month ago. Have done about 2000km since and so far so good. the car is an absolute pleasure to drive now. the only negative is that the intercooler kit you supplied has cheap and nasty hose clamps. you could do better with something decent like t clamps. I have had my intercooler hose come off 2 times already so I will now be replacing all the hose clamps. given the cost of the kit it's irritating to now have to change part of it. Only a small issue but goes straight to reliability.

    Very happy with the customer service from Ultimate Diesel. My vehicle was in for a custom tuning and there were a few issues with my Turbo. The technician went out of his way and spent a few extra hours on it to try and give it the best possible outcome. Have rebooked in another service to recheck everything again at their request which was above and beyond.

    The initial research to have my 200 Series tuned with chip and exhaust was pretty extensive, I didnt want to just throw money away and I wanted it done correctly.
    I eventually decided to go with Ultimate Diesel Tuning and so glad I did. The team there were great to deal with and they discussed with me what to expect in relation to improvements to the vehicle.
    I was initially a bit skeptical but after driving it for the first time after the work I was shocked. It feels like a completely different car. The power is instant there is no lag and is significantly more dominant than before the tune.
    I havent had a long enough trip to be precise on fuel consumption but it is definitely reduced compared to previous.
    The team walked me through during process and kept me up to date. I had an oil leak which I couldnt find which was annoying they found it and fixed this for me while they were doing the tune.
    I would recommend Ultimate to anyone who is looking for a good reliable tune any day, I also intend on returning for all works I cannot do myself.
    Very Happy

    Very easy to deal with, great team.
    I’ve gained power, torque and I’ve almost doubled my fuel range.

    N80 was previously sluggish. Now responds instantly and drives like a $60k turbo diesel should. Was getting 12Litres per 100k, now get an avg of 6.7 litres per 100k. Have had the tune for 4 months and done just over 6000km with it on. Absolutely worth every cent.
