That's almost Z06 levels of performance.

Engine tuning specialist O.CT Tuning has unveiled an aftermarket upgrade program for the Corvette Stingray Convertible. In stock form, the Vette's 6.2-liter supercharged V8 is rated at 455 hp and 460 lb-ft of torque. In partnership with Edelbrock, O.CT Tuning now gives owners the chance to boost output to 621 hp and 612 lb-ft of torque (which is almost Z06 levels of power) thanks to a remapped ECU, bespoke compressor kit, and modified intercooler. Other optional goodies include 22-inch alloys and a stainless-steel exhaust with valve control.
