About the remap

Stage 1 chip tuning for the Audi RS4 2.7 V6 Biturbo 380hp increases power from 380 to 433 hp (+53 hp, +14%) and torque from 440 to 570 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 Bosch ME7 ECU (engine code ASJ / AZR) via the OBD2 diagnostic port – no ECU removal required. We use Alientech KESSv2, ByteShooter Toolbox, CMD CMDFlash 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.
