Not sure which engine you have?

The badge alone is not enough: in this generation, the same engine designation came in different power outputs, each with its own calibration. Check the power output in your registration document and find the matching row.

Hummer H2 tuning: what changes

More power and torque without an ECU remap or replacing any parts. The tuning module only adjusts the engine sensor signals. Your manufacturer’s warranty is preserved: the ECU software is never changed, and the module can be removed at any time.

Questions

Hummer H2 chip tuning: questions

Which tuning module do I need for the Hummer H2?

All engines in this generation are naturally aspirated, so you need 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.
