Conservative ECU Tuning Causing Power Loss On 2015 Chevrolet Corvette Z06

There’s no denying that the 2015 Chevrolet Corvette Z06 is one heck of a performance bargain, with the $78,995 coupe (or $83,995 convertible) coming with a supercar-like 650 horsepower and 650 pound-feet of torque straight out of the box. Now that the first examples have been delivered, some owners are discovering that there are some factory-installed limits on how much fun they can extract from their cars.

Some Z06 owners have reported that they’re experiencing a power loss in their cars after running multiple laps on a track or back-to-back acceleration runs on the highway. This led many to believe that the Z06’s 6.2-liter LT4 V-8 may be losing power due to supercharger heat soak, but it turns out that the culprit is actually conservative ECU tuning.
