About the remap

Stage 1 chip tuning for the Seat Leon 2.0 TFSI 280hp increases power from 280 to 367 hp (+87 hp, +31%) and torque from 350 to 470 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 Simos 18 ECU (engine code CJX) via the OBD2 diagnostic port – no ECU removal required. We use Alientech KESS3, Alientech KESSv2, Autotuner Autotuner and other professional tools. Results are verified with a dynamometer measurement.

Stage 2 is also available for the Seat Leon 2.0 TFSI 280hp – the next level of optimization with even more significant power gains. Stage 2 involves ECU calibration tailored to modified intake and exhaust systems. Consult our specialists to evaluate the potential.

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.
