GAN tuning module for the Pontiac G8

Pontiac G8 tune: what changes

More power and torque with no ECU flash and no new parts – the module only adjusts the engine sensor signals. Your factory warranty is preserved: the ECU software is never changed, and the module can be removed at any time.

FAQ

Pontiac G8 tuning FAQ

Which tuner do I need for my Pontiac G8?

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.
