The 2015 Corvette Z06 is supposed to be batshit nutballs insane on the track. But thanks to emissions regulations that force a conservative ECU tune, the 650 horsepower insane machine is experiencing some issues after heavy use.
After several laps on the track or a few hard acceleration runs on the highway, owners of the brandy new Super Vette are reporting noticeable power loss from the supercharged LT4 V8. Originally it was thought that it was heat soak from the supercharger, but, it is, in fact, conservative tuning of the ECU to help the drivetrain survive for 100,000 miles as well as allow the Z06 to meet stringent US emissions regs.
Chevy knows that this is happening, but feels that almost every Z06 owner will be totally satisfied with their car, and if they aren't, there are aftermarket tuners that they can go to that'll gladly liberalize that ECU to give it more unrestricted power and loosen up its views on the legalization of marijuana.
