Remote ECU tune · 6.2L LS3 V8
A custom Stage 1, 2 or 3 calibration for your Chevrolet Camaro SS LS3, built by hand by a real tuner from your own stock file and datalog, and back with you within three hours of the file arriving. We tune these cars remotely, worldwide: you read and flash with your own HP Tuners interface, and you pay only once the tune is delivered.
Stock vs tuned
From the factory the Chevrolet Camaro SS LS3 makes 426 hp and 420 lb-ft (570 Nm). A Stage 1 tune typically adds 20–35 hp and 15–26 lb-ft, for around 446–461 hp in total. With bolt-ons and a Stage 2 calibration that grows to +65–90 hp, and a Stage 3 build — adding a supercharger or other forced induction, with the fuelling to support it — typically lands at 566–676 hp.
