Questions

Buick Lucerne chip tuning: questions

Which tuning module do I need for the Buick Lucerne?

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.
