What is the difference between a Stage 1 and Stage 2 remap?

A Stage 1 remap is a software-only modification for a vehicle in standard specification. A Stage 2 remap is for vehicles with hardware upgrades such as an uprated intercooler, performance exhaust or induction kit. A Stage 1 calibration will continue to function with Stage 2 hardware in place, but it will not be written to take advantage of those components. A Stage 2 remap is calibrated specifically around the hardware fitted, ensuring the full benefit of that investment is utilised
