Well that didn’t take long. One of the first 2015 Corvette C7 Z06s delivered to a customer is now modified. You’ll likely recall the video we posted just a few days ago of a brand-new Z06 lighting up its tires in a dealership parking lot. Well the owner, Vengeance Racing, has completed its first tune on the Vette’s 6.2-liter, supercharged V-8.

The racing shop located outside Atlanta, GA fitted the car with a high-flow cold-air intake system, swapped out the supercharger’s pulley for a larger one, and programmed in its own ECU tune. The results are pretty impressive.

The base dyno run reveals the car makes 587 horsepower and 611 pound-feet of torque at the rear wheels. That’s not too far off the 650 horse and 650 pound-feet at the crank promised by GM. After swapping in some minimal parts, the Vette gained another 75 horsepower and 60 pound-feet of torque.

The new specs sit at 660 horsepower and 663 pound-feet of torque.

Keep in mind those modifications were made without any internal engine work — just a different air intake and a pulley swap, both of which are bolt-on applications. An ECU tune is usually a plug-and-play operation, but Vengeance did have to develop the tune itself.

It’s likely this isn’t the limit to Vengeance’s work on the car. A camshaft and fuel injector swap, headers, and a more free-flowing exhaust should boost power beyond the 700-horse mark. Lookout Hellcat!

The Corvette Z06 is now the baddest Vette ever made. Sporting 650 horsepower and 650 pound-feet of torque right from the factory, the Z06 hits 60 mph in just 2.95 seconds when equipped with the new eight-speed automatic transmission. The seven-speed manual gets the job done in 3.2 seconds. The quarter mile comes in at 10.95 seconds and 11.2 seconds, respectively.

Besides the supercharged, 6.2-liter V-8, the Vette also has tenacious cornering abilities thanks to its lightweight design, active aerodynamics providing downforce, and its sticky Michelin Pilot Super Sport 2 tires.

Pricing for the Z06 starts at $78,995 and goes north with options.
