About the remap

Stage 1 optimization for the Chrysler 300C 5.7 Hemi V8 340hp increases power from 340 to 363 hp (+23 hp, +7%). 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 Motorola NCG4 ECU (engine code 5.7 Hemi V8) 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.
