    Took my laggy mn triton in to the Dandenong shop for a de-soot and tune, I don't think I got the right car back because the power and torque they got out of the ute was fantastic! These guys have great customer service and I would highly recommend them to any of my friends and family!

    Took my new sr5 in for a tune and had great results. Went back for 3" exhaust, npc clutch and retune and couldn't be happier. Great workshop with plenty of knowledge to share!

    Booked car in for desoot, catchcan and snorkel.
    They rang me to say the Car intake was clean and wouldn’t charge me or rip me off on price, which was good to hear, instead done an oil change and fuel filter.
    Highly recommend the boys at Dandenong, Great service

    Just picked up my DMax from Ultimate Diesel Tuning at Geebung after having had it's Manifold soot clean-out, a system re-map and Dyno Towing Tune and, they weren't kidding when they told me I would notice a major difference in performance and responsiveness.

    Wow. It’s like, better than when it was new.

    The graph shows that their work has led to a 39% increase in kWs power at the wheels and a 46.06% increase in Nm torque.

    I can't wait to see how the fuel economy improves. My fuel consumption up until now (December 2014 to November 2019) has averaged 11.08 litres / 100 Kms.

    Looking forward to this being around the low 9's.

    Just had an all rounder tune done to my 2015 76 Cruiser, and can’t speak highly enough about the end result or the service. Great bunch of guys who went out of their way to make sure I was happy, and the car is so much better for the tune. Better fuel economy, massive power gains at a useable rev range, and new clutch to suit the extra power. Can’t wipe the grin off my face!
