GAN tuning module for the Cadillac ATS

Cadillac ATS 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

Cadillac ATS tuning FAQ

Which tuner do I need for my Cadillac ATS?

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.
