Built for BTR Stage 3 Camaro SS Setups
A Stage 3 cammed LS3 or L99 Camaro 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 2010-2015 Camaro SS LS3 manual and L99 automatic 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
- Revisions included because real tuning takes testing, logs, communication, and adjustment
- Requires HP Tuners hardware/software and credits where applicable
