Stage 1 remap figures
A Stage 1 remap is a software-only change to the ECU on an otherwise standard car. It needs no extra parts, which makes it the usual starting point.

Who is the Stage 1 map for?
- Drivers who want a noticeably quicker car from a software-only change, with no new parts.
- Daily drivers who want stronger mid-range pull and a sharper throttle.
- Anyone who wants the biggest gain we list without fitting hardware.
What this means for your Cayenne
On a turbocharged petrol engine a remap adjusts boost, ignition timing and fuelling together, so both power and mid-range torque rise and the car pulls harder out of corners and junctions.
Engine management is by a Bosch ME7.1.1 unit. Older engine management is simpler to work with, but age matters: worn sensors, leaks and tired components can hold back what a remap delivers, which is why we run a diagnostic check first.
We remap at our Belgrave Gate workshop in Leicester, or at your home or work within 30 miles, and every job starts with a diagnostic check.
Please note: these are expected figures, not guarantees. Real results vary with the condition of the vehicle, the ECU software version, fuel quality and the hardware fitted. Some options - including Stage 2 and anything that needs extra hardware - are for off-road or competition use only. We check every vehicle first and confirm what is achievable before any work starts.

Stage 1 questions
How much power does the Stage 1 map give the Porsche Cayenne Turbo 450bhp?
We expect 525bhp and 733Nm against 450bhp and 620Nm as standard: up to +75bhp and +113Nm. These are expected figures, and we confirm what is achievable on your own car after a diagnostic check.
Does a Stage 1 remap need any extra parts on the Porsche Cayenne Turbo 450bhp?
No. Stage 1 is a software-only change to the ECU on an otherwise standard car.
Is there a gentler map than Stage 1 for this engine?
Yes, two. Stage 1 Eco is performance with economy in mind: 506bhp and 724Nm expected. The Eco map is economy first: 500bhp and 718Nm. Both still sit above the standard 450bhp and 620Nm.
Do I need to tell my insurer about a remap?
Yes. A remap is a modification, so you should declare it to your insurer.
