About the remap

Stage 1 optimization for the Porsche 911 4.0 GT3 RS 520hp increases power from 520 to 541 hp (+21 hp, +4%). Naturally aspirated petrol engines have limited scope for power gains, but optimizing ignition and fueling maps delivers a smoother power delivery, more responsive throttle, and a noticeably more pleasant driving experience.

The remap is performed on the Bosch MED17.1.11 ECU (engine code MDG.GA) via the OBD2 diagnostic port – no ECU removal required. We use Autotuner Autotuner, CMD CMDFlash, Dimsport New Genius and other professional tools. Results are verified with a dynamometer measurement.

Every vehicle undergoes full diagnostics before and after the remap. We keep a backup of the original ECU calibration and guarantee the option to revert to stock settings at any time. JVK PRO is a professional chip tuning service in Riga with 16 years of experience.
