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 Gen V LT1 and LT4, and 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
How to Get Tuned
Own an HP Tuners MPVI interface? Our GM email tune is the fastest path. Buy it, read your own PCM, send us the file with your mod list, and we email your finished tune back in 24 to 48 hours. Nothing ships, your truck or car never comes off the road, and every platform we list reads and writes through the OBDII port with no send-in unlock service required.
Don't have an interface? Order a mail-order custom tune, ship us your PCM, and note your setup at checkout. We tune it and send it back ready to run. Prefer a live session? See our on-site dyno tuning.
