About This Product
2008-2009 Pontiac G8 GXP LS3 BTR Stage 3 Cam Tune
This tune file is built for the 2008-2009 Pontiac G8 GXP 6.2L LS3 running a BTR Stage 3 camshaft. Select any additional mods on your car below, then add the tune package to cart. We build the calibration around your factory read file, operating system, transmission, cam setup, and full mod list. This is built for aggressive cam behavior, clean startup, stable idle, strong drivability, better throttle response, and real revisions until the car is right.
Built for BTR Stage 3 G8 GXP LS3 Setups
A Stage 3 cammed LS3 G8 GXP needs more than a basic file. The airflow, idle, fueling, spark, torque management, and transmission behavior need to be corrected so the car starts clean, holds idle, drives smooth, and still delivers the aggressive cam character people want.
- Built for 2008-2009 Pontiac G8 GXP 6.2L LS3 cars
- Designed specifically for BTR Stage 3 camshaft setups
- Supports common bolt-ons like headers, intake, exhaust, converter, injectors, E85, and gear/tire changes
- Built from your actual factory read file, not a random one-size-fits-all upload
