Ranger PX — Stage 2 ECU Tune
- 75% increase in power output
- 89% increase in torque delivery
- Enhanced turbocharger efficiency
- Improved intercooling performance
- Optimized engine breathing with snorkel integration
This Stage 2 PX Ranger runs a Garrett turbo paired with a quality intercooler, full exhaust system, and upgraded piping. The combination brings the 3.2L diesel from 94 kW to 127 kW at the wheels, with torque lifting from 364 Nm to 447 Nm.
The calibration pulls useful mid-range grunt, which is where these trucks spend most of their time when towing or loaded on long highway runs. The supporting hardware does the heavy lifting on thermal capacity and flow, letting us dial in the file without running into heat or pressure limits under sustained load.
It's a sensible build for owners chasing better overtaking response and towing confidence without going too far down the rabbit hole.
Is 447 Nm safe for the standard gearbox and driveline?
The gain is moderate and well within what these drivetrains see regularly when towing near GVM. It's not a grenade pin, but how the truck is used and serviced will always matter more than peak figures.
Why is the intercooler and exhaust work necessary for Stage 2?
The factory cooler and exhaust choke airflow once you exceed stock boost and fuelling. Without them, you'd see heat soak and backpressure limit what the tune can safely deliver under load.
What kind of real-world difference does 33 kW make in a Ranger?
You'll notice it most when merging under load or holding speed on inclines with a trailer hooked up. It's not a night-and-day transformation, but it takes the strain out of overtaking and climbing.
