    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

    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.

    Had both my 08 Navara STX 2.5 and wifee's Pathfinder 550 V6 done by these guys. Both had 3" exhaust replacements and intercooler on the Nav all done in house. Both go better than I thought any diesel could!!

    Better economy, except maybe when enjoying the torque rush too much, different vehicles to drive in the best way.

    Thanks Brad and the team. 2 very happy customers.

    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.

    Took my MR Triton in for a bit of a tune and the results were amazing. Plenty of power and torque at the pedal with great response. Would go back to these guys anytime or recommend just as much. Customer service was great everyone was friendly and helpful. Great job guys, Thanks again

    Got a 3inch exhaust and tune on my 2015 dmax today. It's like a different car, massive difference in the power, way less lag, sounds amazing. Couldn't be happier. 10/10 would recommend to anyone
