We are Supreme Conversions, your Authorised Pendle Performance Agent for Shropshire and North Wales,
Engine ECU and Transmission TCU tuning available for your Volkswagen Transporter, Caddy or Crafter.
Supreme Conversions reads and writes your vehicle’s ECU with professional equipment. Every file is custom calibrated at Pendle HQ – the same Pendle calibration, closer to home.
Calibrated at Pendle HQ
Supreme Conversions reads your ECU and the file comes to Pendle HQ, where it is custom calibrated in WinOLS – torque, fuel, boost and timing together as one. It goes back to be written to your vehicle.
Correct OEM calibration: smooth power, inside the engine’s safety limits.
Checked with a Data Log
Every vehicle is data logged before and after the tune, and every log gets an in-depth data log report: boost requested against delivered, fuelling and rail pressure, across the whole rev range.
Proven on the road
The dyno proves the power; the road proves the calibration. Our Road Drive Report shows the linear delivery, the smooth uptake of performance and the drivability – everyday driving, where a calibration is felt most.
