Over 550whp on tap, and sporting a new form of fun hidden under the skinny pedal, Don’s 2017 Chevrolet Corvette Grand Sport is one killer daily driver. While the LT1 is a great performance engine in its own right, Don desired more, so a plan was implemented to add something most every C7 owner wants under the hood…..BOOST!

With the mechanical work wrapped up in the shop by John, Matt strapped her down to the rollers for Vlad to perform a custom calibration via HP Tuners. With 93 octane in the tank, and the Vortech YSi delivering ~9psi, Vlad increased the LT1’s output to a solid 571.37whp & 554.79lbft! Some pretty outstanding numbers considering this C7 is still on the stock fuel system!
