At MoreBHP HQ in Crewe we develop and test our remaps on a state of the art 1200bhp 4WD rolling road.

By adding a rolling road session to your Stage 1, Stage 2 or ECO remap you can see what power / torque your car makes both before and after the upgrade.

Using live diagnostics this allows us to custom tune the remap to your vehicle.

If booking at More BHP HQ in Crewe then this option is highly recommended.
