Mercedes-Benz GLC X253 remap: what changes
The GAN box plugs in between the sensors and the engine control unit (ECU) and adjusts their signals, while a flash remap rewrites the ECU itself. Your manufacturer’s warranty is preserved: the ECU software is never changed, and the box can be removed at any time.

Mercedes-Benz GLC X253 remap: common questions
Which tuning box do I need for the Mercedes-Benz GLC X253?
Every engine in this generation is turbocharged, so it takes the GAN GT or GAN GTL. Find your engine in the table above – each row shows the box and its price.
Is a tuning module the same as a Stage 1 remap?
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.
