What Stage 1 involves
Stage 1 is for a standard car with nothing fitted. We read the original file off the ECU, write a calibration developed for the 450ST 14.95L 452hp (332kW) 2244Nm, then road or rolling road test it before handing the car back. Nothing is added and nothing is removed, so it looks and services exactly as it did.
It takes most of a day. We keep your original file, so it can go back to standard at any point. Figures here are for a healthy 450ST 14.95L 452hp (332kW) 2244Nm, and we check the car over before writing to it.
