FAQ

Porsche Boxster 987 tuning FAQ

Which tuner do I need for my Porsche Boxster 987?

Find your engine in the table above – each row shows the tuner and the price.

Is a tuning module the same as a Stage 1 tune?

Not quite. Stage 1 usually means an ECU flash tune without replacing any parts. The tuning module also works without replacing parts, but it does not change the ECU software: it adjusts the sensor signals, comes off in about a minute, and the OFF button in the app restores the factory settings.
