GM LS & LSx V8 Custom Tuning
SBR Performance builds custom, dyno-developed tunes for GM's LS and LSx family of V8 engines. Whether you're chasing bolt-on gains, cleaning up a swap, or backing up forced induction, we calibrate your PCM to your exact combination — using the same expertise behind our full GM tuning lineup.
Engines We Tune
The complete LS/LSx range — 4.8, 5.3, 6.0, 6.2, and 7.0L (LS7), across Gen III and Gen IV, plus Chevrolet Performance E67 and E92 crate-engine PCMs.
Popular LS-Powered Vehicles
- Chevrolet Camaro (2010–2015 6.2 / 7.0 / SS) and Corvette (C5 / C6 / C7)
- Pontiac GTO, Pontiac G8, and Chevrolet SS / Caprice PPV
- Cadillac CTS-V and Chevrolet TrailBlazer SS
- Silverado, Sierra, Tahoe, Suburban, Yukon, and Escalade — see our GM Truck & SUV tuning
What a Custom LS Tune Delivers
- Optimized spark and fuel for your octane and mods (intake, headers, cam, heads)
- AFM / DoD (cylinder deactivation) delete for reliability
- Removal of factory torque management, speed limiter, and rev limiter as needed
- Tuning for forced induction and nitrous
- Corrections for tire size, gear ratio, and torque-converter lockup
