    Took my 2014 Triton into the Geebung store in Brisbane for a desoot treatment, 3 inch stainless exhaust, KnN filter, catch can and a tune. Couldn't be happier with the job. Car drives much better with improvement across the board. They had all the time in the world for me before I booked it in and didn't try bull shit or push me towards certain products. I highly recommend them and will be going back in the future too. Thanks guys.

    Money well spent. My Amarok went from 0-100 in 11.7sec to 9.1. Towing my 23ft 3t caravan to 1770's got 14.7ltr/100k

    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.

    Great service with a loan car and my 79 series now runs like a V8 was made to. Has better performance and reduced fuel consumption.

    Down from 12.7 to 8.4L per 100k on the freeway, power and responsiveness changes makes it feel like a completely different Jeep. Thanks for the awesome work guys.

    Staff at the Geebung store are awesome and always willing to go that extra mile. Keep up the good work lads and i couldn't be happier with the power figures after your tuned on my 4wd.

    I've a 2015 Gu Patrol - everyone knows they're the best 4wd around aside from maybe a little lacking in the power department...!
    Picked it up last night, and apart from now being able to actually overtake another car on the highway, I reckon it could almost do a skid if I wanted it to. Stoked with the result, couldn't be happier. Even got a free t-shirt �

    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.

    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!

    The team at Ultimate Diesel are exceptional. They were professional whilst conducting my service and treated the four wheel drive as if it was their own. Their customer service is second to none. I would highly recommend to anyone if you need to have your diesel serviced or are considering getting a tune.
