What owners say

What Porsche 911 owners say about GAN

★★★★★

Simple and convenient. Satisfied with result. I connected this device via the attached cable and hid it behind the pile floor covering.

FAQ

Porsche 911 991 tuning FAQ

Which tuner do I need for my 911 991?

Every engine in this generation is naturally aspirated, so you’ll want the GAN GA or GAN GA+. 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.
