  • Fueling, spark, idle airflow, and torque model corrections
  • Converter-friendly drivability changes
  • DOD/AFM disabled where applicable

Best For These Builds

  • Stage 2 cam builds with headers and street manners

  • Long tube headers, intake, exhaust, injectors, and converter changes
  • LS1, LS3, L99, LT1, LT4, and aggressive truck builds

Converter Warning

Some Stage 2 and most Stage 3 cam setups may need a higher stall converter depending on vehicle weight, gearing, cam specs, and intended use. Text your exact cam specs and build details before ordering if you are not sure.

Stage 2 and Stage 3 Cam Tune Files for GM LS and LT Builds

A Stage 2 cam tune file or Stage 3 cam tune file is built for more aggressive camshaft setups that need more than basic bolt-on tuning. Larger cams change idle airflow demand, vacuum, fueling behavior, spark needs, torque modeling, and transmission behavior.

J.R. Jones Racing builds Stage 2 and Stage 3 cam tune files for LS1, LS6, LS3, L99, LT1, LT4, Gen III trucks, Gen IV trucks, and higher-output LS builds using HP Tuners.
