Chevrolet Impala tuning FAQ
Which tuner do I need for my Chevrolet Impala?
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.
