ECU / ECM Tunes

Sort by

Dyno-tested, fully custom ECU and ECM tunes from SBR Performance — developed on a real chassis dyno and proven on track by racer Luke Bland. We're best known for our Chevrolet Cavalier and Pontiac Sunfire Ecotec tuning, but we tune a wide range of GM vehicles, plus the Ford Crown Victoria.

Send us your computer for a mail-order custom tune and we'll dial it in to your exact setup — transmission type, fuel octane, camshafts, bolt-ons, or forced induction. Coverage spans nearly the entire GM lineup:

Makes: Chevrolet, GMC, Buick, Cadillac, Pontiac, Saturn, Oldsmobile, and Hummer (1997–2019)
Cars, trucks, SUVs & vans — from Cavalier, Cobalt, Malibu, Impala, and Grand Am to Silverado, Sierra, Tahoe, Suburban, Camaro, Corvette, and Express
Engines: 2.2L & 2.4L Ecotec, 3.1–3.9L V6, and LS/LSx V8 (4.8/5.3/6.0/6.2/7.0)

For the Cavalier/Sunfire Ecotec we also offer pre-tuned, ready-to-run ECUs (2002 push rod, 2003–2005 Ecotec, and 2.4L hybrids) — no core-swap headaches, just plug in and drive.
