Alfa Romeo 147 tune: what changes
The module plugs in between the sensors and the engine control unit (ECU) and adjusts their signals. It never rewrites your ECU software: your factory warranty is preserved, and the module can be removed at any time.

Alfa Romeo 147 tuning FAQ
Which tuner do I need for my 147?
Turbo engines take the GAN GT or GAN GTL; naturally aspirated engines take 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.
