About the remap

Stage 1 optimization for the Ferrari 355 GTS/GTB/Spider 3.5 V8 380hp increases power from 380 to 402 hp (+22 hp, +6%). 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 M2.7 ECU (engine code F129B/40) via the OBD2 diagnostic port – no ECU removal required. 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.
