About the remap

Stage 1 optimization for the Maserati Quattroporte 4.7 V8 430hp increases power from 430 to 448 hp (+18 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 ME7.3.2 ECU (engine code M 139R) using the Bench/Boot method with direct ECU connection. We use ByteShooter Toolbox. 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.
