Great job on the new clutch and tune in my 79 series dual cab. It’s like having a new car. Lots more power at a safe level. Engine temps have not changed at all. Highly recommend Great work guys!!!

Rob - Toyota Landcruiser 79 Series

Got my 2019 dmax tuned from these guys and had a few services done, drove it across Australia and still going strong. The tune made it feel like I was driving a different car. Fuel economy and performance gains was way above what I was expecting.

Chase - Isuzu DMAX

Took my 76 in for new injectors plus tune. They put in the time and effort to drive it between tune and make sure it was perfect, and it definitely is! Absolutely stoked with the outcome!

Zac - Toyota Landcruiser 76 Series

Can't fault any of the work that Reuben and the boys have done. Took my hilux rogue in for a remap, eshaust and trans tune. Couldn't have got a better result. Done on time, fair pricing and work is very professional.

Kane - Toyota Hilux Rogue

Great work by the lads at RMR, Had a few issues with my VW transporter which they sorted no problems. A little tune up as well and she flys. Would highly recommend.

Lee - VW Transporter

RMR did a great job with my manual px2 ranger. Took it in for a dyno tune and they got 37% Horsepower gains and 42% torque gains. The car pulls very hard straight off the bottom, very noticeable difference couldn't be happier with the results.

Josh - Ford Ranger PX2

Ash and the boys took the time to make it perfect. Very happy with the mods , service and communication from the team.Car runs like a rocket now . Highly recommend RMR 4x4.

Why 4WD Owners Trust RMR Diesel

We’ve built our reputation on reliability. From LandCruisers, Hilux and Fortuners to Isuzu, Ford and Nissan diesels. Our spotlight came from mastering the ZD30- the most criticised engine out there- turning it into a reliable, high-performance platform. That alone speaks volumes for what we achieve.

"I've been bringing my car to RMR for the last couple of years... they've always looked after my car really well. It runs amazing... RMR is the way to go."

- Mitch
