About this remap

Chevrolet Corvette ZR1 6.2 V8 S/C 638 bhp Stage 1 — what changes

The Chevrolet Corvette ZR1 6.2 V8 S/C 638 bhp (2005–2013) leaves the factory at 638 BHP and 819 Nm of torque. Manufacturers deliberately detune this engine to separate it from more expensive variants in the range — a Regal Tuning Stage 1 calibration safely recovers that headroom through the ECU alone: no hardware changes, no dyno risk, fully reversible.

Fuelling, boost pressure, ignition and torque limiters are optimised within the safe tolerances of the 6.2 V8 S/C 638 bhp powertrain (petrol). The result is 680 BHP and 875 Nm with factory smoothness, cold-start protection and emissions behaviour retained.
