I just had a tune done on my Next Gen V6 Ranger. The results far exceeded my expectations with both torque & fuel economy. I did not expect the change to be so great especially when not towing. This was the main reason I had the upgrade. I would recommend anyone who wishes to have a upgrade to come and have it done here.

Took my VW Transporter in to Ben for a tune and couldn’t be happier with the result. Ben was very knowledgeable and took the time to explain everything properly, rather than just chasing big numbers. The van has noticeably more power and torque and feels much better to drive, while still keeping the tune sensible and reliable. I particularly liked that Ben was focused on a smooth torque curve and the long-term reliability of the vehicle. Communication was excellent, the service was professional, and you can tell Ben takes pride in his work. Highly recommend to anyone looking for a quality tune. Thanks Ben!

Ben at Sunshine Coast diesel tuning just carried out an ECU ReMap, upgraded intercooler and exhaust on my 2025 Next Gen Ranger. He was great to communicate with and worked in with my busy schedule. I’m very happy with the work he done on my Ute. After reaching out to multiple companies to get the work done on my Ute I’m very happy that I chose Sunshine Coast diesel tuning. Keep up the good work mate

Had a great experience dealing with Ben. He was professional, easy to deal with, and took the time to explain everything clearly. The work was done properly and I really appreciated the effort and attention to detail. Would definitely recommend to anyone looking for someone reliable and knowledgeable.

Frequently Asked Questions

Got questions? We’ve got answers.

A Stage 1 tune typically takes 2-3 hours including dyno runs. Stage 2 tunes may take longer depending on hardware configuration. Typically we like to work on a 1 day turn around dropping off one day and picking up the following day.

No you do not need a vehicle on the dyno we offer remote tuning throughout Australia, we do however dyno tune all vehicles that are booked in at our workshop on the sunshine coast to ensure optimal results and verify power gains. This includes a print out of the before and after runs.

A properly calibrated tune should not produce excessive smoke. We tune for clean combustion while maximising performance. 

Absolutely. We offer dedicated tow tunes that prioritise low-end torque, safe EGTs, and optimal power delivery for loaded conditions.
Yes, we can return your ECU to factory settings at any time. We keep backups of your original calibration.

We perform a health check before tuning. If we find issues, we’ll advise you before proceeding. We won’t tune a vehicle with underlying problems.
