Porsche Boxter GTS ECU remapping

About remapping
This entry groups Porsche Boxster GTS units in our catalogue, with 6 files, split between the 2.5T turbocharged and the 3.4 DFI naturally aspirated flat-six. It is the sporting version of the mid-engined roadster.
Stage 1 makes up 5 files, with one Stage 2. The ECUs are SDI21, SDI9 and SID9. The two engine generations respond very differently: the turbocharged unit has far more headroom.

Which engine gains most?
The 2.5T turbocharged, by a clear margin. The naturally aspirated 3.4 gains considerably less, since there is no boost to adjust.
How does it differ from the Cayman GTS?
They are the coupé and roadster versions of the same car, sharing engines. Each has its own entry in our catalogue.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
