DMS Automotive ECU Tuning | Porsche 997 GT3 RS 3.8

Porsche 997 GT3RS 3.8

ECU Upgrade adds an additional 30hp to the 450hp engine. The 997.2 Porsches are tuned via the OBD 2 port which allows us to access the ECU files without removing any physical parts. The program is completely undetectible by the Porsche dealers diagnostic systems so there isnt any worry regarding factory warranty.
