Our stage 4 ECU custom remap calibration is again a full custom bespoke calibration for the major hardware upgrades including big turbo upgrades for 400+ BHP! For an example, our BMW E91 330D LCI N57 is running a HTD3073BB turbo allowing huge power increase whilst still using the stock engine and fuel system! We will result in fully controlled torque delivery, boost control peak and rail pressure. We will also rework the gearbox flash custom setting via XHP Flash.
