How much power?

Approximate, engine-safe figures for US-market cars. Ready Tune — conservative, with a safety margin. Custom Tune — built on your datalogs, closer to the max your car can take.

All figures are approximate estimates, not a guarantee or a dyno result. Octane is the US pump number (AKI): switch between 93 and 91 above — 91 makes a bit less. Ethanol blends (E30–E85) are Custom Tunes only. Ready Tune numbers assume a healthy car. SUVs keep extra margin for towing and high altitude — in thin air the turbo spins faster for the same boost, so we keep boost and torque in check. Stage 2 needs supporting hardware (such as downpipe, intake or intercooler). Custom results depend on your car's condition, fuel and datalogs. Higher stages are available as Custom Tunes — use “Find my tune” to see every stage for your car.

Tunes by make: BMW · Mercedes-Benz · Audi · Volkswagen · Porsche · MINI · Toyota
