The guys were great. Very happy with outcome. Special thanks too Brad for talking me through and making the right choices. Really does what they say.

Had my hilux in for a tune to help with highway driving as the car had no power up hills and high exhaust temps. After picking up the car and taking it for a drive it feels like a totally different car awesome thanks guys

Very informative explanation of procedures in tuning my car and the staff were knowledgeable and courteous.

The service was awesome, and the outcome was better than we expected..! So happy..!

Thanks to Drew and the team at ultimate diesel in Dandenong nothing was to much trouble with them great tune on my sportscat for great service and communication with myself highly recommended these boys if you’re after a tune on your vehicle. 👍👍

Not long put my 200 series in for a soot clean and catch can remap and therom fan’s on the inter cooler and the performance is so much better . Thanks to rob and the boys, if you’re thinking of an up grade see these guys

James and the team at Ultimate Diesel Tuning at Geebung are awesome, i recently had my N80 Hilux in for the Ultimate Torque pack, remap and Torque converter lock up kit on the transmission. 48% more power and 45% more torque make it so much nicer to drive. So much better response on the accelerator and no more lag. Makes going up hills a breeze and holds its power and wants to keep going and loves it. I drove it down from Townsville and left it with James and they were happy to look after it for a couple of weeks because i couldn’t get back straight away. When i flew back in they had it ready early on the Friday for me. I then drove it back to Townsville some 1300km and gave it a workout on the way and still saved about 1.5L/100km then i did on the way down I can’t wait to Tow my Caravan. Great Friendly service and a professional job. Thanks Darren

After recently having my Ranger PX11 engine flushed, tuned, new larger inter cooler and catch can installed for caravan towing I was presented with a copy of the dyno runs both before and after. To be completely honest the gains made didn’t really click with me until I drove home. Very impressive it’s improved drivability out of sight. Highly recommend the work these guys do.

Amazing stuff got to meet rob from ultmate diesel at the 4×4 show expo they give really great grains amd power amd torque they al so do things for Your engine protection 💕🙊😘💜

Had my 2018 rugged x at the geebung shop for a complete dyno tune and soot clean complete with a catch can and i can say the performance is incredible i totally recommend the guys and the team if u need your 4wd professionally tuned i will be definitely going back in the near future to get more work done

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.

Dandenong team were fantastic and results surpassed expectations. Booking and follow-up very customer focused – will be back as have other needs.

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.
