About the remap

Stage 1 chip tuning for the Dodge Challenger SRT 392 6.4 V8 485hp increases power from 485 to 507 hp (+22 hp, +5%) and torque from 644 to 665 Nm. Turbocharged petrol engines respond exceptionally well to ECU optimization – adjusting ignition timing, boost pressure, and fueling maps unlocks the hidden potential built in by the manufacturer.

The remap is performed on the Siemens GPEC2A ECU (engine code 6.4 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.
