The Camaro LS3 has more in it than the factory ECU was ever going to release.
The Chevrolet Camaro LS3 and its platform-mates share a factory ECU that prioritizes emissions and averaged-out reliability over what the engine can actually do. The Boomslang PNP Wiring Harness for the Haltech Nexus / Rebel LS connects directly to your factory harness without any permanent modifications, giving the Haltech Nexus / Rebel LS full standalone engine control. No cutting, no splicing, fully reversible.
