Subaru Impreza WRX II chip tuning: questions
Which tuning module do I need for the Subaru Impreza WRX II?
All engines in this generation are turbocharged, so you need the GAN GT or GAN GTL. Find your engine in the table above: each row shows the module and the price.
Is a tuning module the same as a Stage 1 tune?
Not quite. Stage 1 usually means an ECU remap 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.
