Porsche Cayenne 4.2 V8 Diesel Stage 1

This Porsche Cayenne 4.2 V8 diesel went from 382hp and 850Nm to 450hp and 950Nm with our Stage 1 calibration, a gain of 68hp and 100Nm.

A V8 diesel that tows anything

The owner wanted more from the big V8 diesel, and with 950Nm on tap it will now tow just about anything with ease. Stage 1 sharpens the response and adds strong pull through the mid-range while keeping the Cayenne smooth and refined.

Add-ons

  • Speed limiter solution

Is a Cayenne V8 diesel good for towing after a remap?

Yes. The extra torque makes heavy loads feel lighter and overtaking easier. We tune Porsches at your home or workplace across Bristol, North Somerset, Somerset and South Wales.

About this job

The results

Power went from 382hp to 450hp, an increase of 68hp or around 18%.

Torque rose from 850Nm to 950Nm (+100Nm), which is what you feel most in everyday driving: stronger pull from low revs and easier overtaking.

What the work involved

A Stage 1 remap is a software calibration for an otherwise standard car. We refine parameters such as boost, fuelling, ignition timing and torque limits within safe margins, so it pulls harder through the mid-range without any hardware changes.

How we carried it out

  • Diagnostic scan for stored faults before any work
  • Stabilised power supply connected while programming
  • Original software read and saved, so the car can be returned to standard
  • Calibration written, then the car checked again afterwards
