Stage 2 Tuning

Stage 2 tuning includes custom chiptuning and additional hardware parts, usually related to intake and/or exhaust. Indicated power ratings may vary depending on a number of factors including the specific parts used, their combinations, fuel quality, measuring equipment and environmental factors.

Stage 3 Tuning

Stage 3 tuning goes another step further with more elaborate hardware upgrades including parts like more capable turbochargers, injectors and/or even engine internals and custom-developed chiptuning to complement the hardware changes and make the best use of the new ability. The power rating greatly depends on the ability and combinations of the aftermarket parts installed.
