GMC Sierra tuning: what changes

The tuning module sits between the sensors and the engine control unit (ECU) and adjusts their signals. Your manufacturer’s warranty is preserved: the ECU software is never changed, and the module can be removed at any time.

Questions

GMC Sierra chip tuning: questions

Which tuning module do I need for the GMC Sierra?

Turbocharged engines take the GAN GT or GAN GTL, naturally aspirated ones the GAN GA or GAN GA+. 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.
