About This Product
LS1 Stage 2 Cam Tune File
This is a pre-written performance tune file built for 1998–2002 GM LS1 vehicles running a Stage 2 camshaft setup including Texas Speed, BTR, Sloopy Mechanics, and similar cam profiles.
Designed around common 220–228 duration, .585–.610 lift, 112–114 LSA LS1 cam setups, this calibration delivers stable idle control, corrected airflow, improved fueling, stronger throttle response, and smooth drivability with aggressive cammed LS1 performance.
This is not a generic file. Your tune is built around your factory read file, operating system, engine, transmission, injector data, cam setup, and full modification list.
Stage 2 LS1 Tune Built for Real Street Driving
Stage 2 LS1 cam setups are one of the most popular performance builds, but they require proper calibration. Stock tunes struggle with idle instability, airflow mismatch, poor drivability, and incorrect fueling after a cam swap.
