Porsche 991 GT3 RS ECU remapping
10 files available
About remapping
The Porsche 991 GT3 RS accounts for 10 files in our catalogue, entirely the 4.0 DFI naturally aspirated flat-six. It is the most track-focused version of the 991-generation 911, one step beyond the GT3.
Every one of the 10 files is Stage 2 — the only entry in our catalogue with no Stage 1 at all. It reflects a car that always arrives with hardware already modified. The ECU is a single reference: MED17.1.11.

Why is everything Stage 2 here?
These cars are used on track and always arrive with exhaust hardware already fitted. Stage 2 is what takes advantage of it.
How much does a naturally aspirated engine gain?
Considerably less than a turbocharged one — there is no boost to adjust. Expect refinement in delivery rather than a large power figure.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
