Calibration detail
What We Optimised
The Isuzu MU-X 3.0L diesel earns loyal fans for reliability but consistently draws criticism for underwhelming power delivery — especially under load. This 2015 automatic came in at 37,000 km producing 125hp and 336Nm at the wheels.
A custom remap targeting boost, fuel delivery, cam timing, lambda and pedal position unlocked 33hp and 116Nm at the wheels — a 26% and 35% gain respectively. The torque improvement is particularly significant for a seven-seat SUV that owners regularly use for touring and towing.
At 158hp and 452Nm tuned, the MU-X now tows with genuine confidence and pulls cleanly through steep grades. It's the off-road-capable family tourer its body always promised to be — just with the engine calibration it should have shipped with.
Raised and shaped to match the compressor map — no surge, no lag
Common rail pressure optimised for combustion efficiency across the rev range
Injection timing advanced at mid-range for better torque response
Air-fuel ratio monitored and calibrated on the dyno — not estimated
Throttle response recalibrated — no dead spot off idle, linear and predictable
Conservative exhaust gas temperature ceiling maintained throughout
Properly calibrated combustion means less fuel burned to reach the same torque at cruise. Most owners report 8–15% better highway fuel economy after the remap — with no hardware changes required.
Every remap is verified on our in-house Mainline dyno. You receive the actual before/after charts with your car's numbers.
Your factory file is backed up before we start. We can restore the original tune any time — for dealer service or trade-in.
Stock exhaust, stock injectors, stock turbo. All gains come from the calibration — nothing on your car needs to change.

Got my Ranger PX2 tuned here. Massive difference in throttle response and pulls way harder up hills with the caravan. Workshop is spotless and the lads explain everything. Worth every cent.
Booked online, dropped the car off in the morning, picked it up after work. Honest quote, no upsell, and the difference in my Q5 is night and day on the freeway.
Drove down from the Central Coast for these guys and it was worth every km. Smoother, stronger, and using less fuel on my run home. Highly recommend to anyone with a diesel.
Had my LandCruiser 200 Series tuned. Completely transformed — towing my horse float is effortless now. These guys know diesels inside out. Factory file backed up, zero risk.
BMW X5 30d done. Was nervous about voiding warranty but they explained everything, backed up the original file, and the result on the freeway is outstanding. Fuel economy actually improved.
My D-Max had a DPF and remap done the same day. No drama, no upsell, dyno sheets handed over when I picked up. The before/after numbers speak for themselves.
