8 files available
About remapping
The Porsche Cayman GT4 accounts for 8 files in our catalogue, split between the 3.8 DFI and 4.0 naturally aspirated flat-six. It is the track-focused version of the mid-engined coupé.
Stage 1 accounts for all 8 files, with one speed limiter removal alongside. The ECUs are SDI9 and MG1CP007. Being naturally aspirated, the gains here are modest by nature.

How much does a naturally aspirated engine gain?
Considerably less than a turbocharged one — there is no boost to adjust. We are honest about this: expect refinement in delivery, not a large power figure.
How does it differ from the Cayman S?
The GT4 is the track-focused version, with a larger naturally aspirated engine and specific chassis work. Each has its own entry.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
