With the mechanical work wrapped up in the shop, John strapped her down to the rollers for Vlad to perform a custom Flex Fuel calibration via COBB Tuning's Accessport V3. With 93 octane in the tank, Vlad increased output to a conservative 330.62awhp & 345.89lbft, and then with E85 in the tank and the stock turbocharger at full tilt, output increased to a ripping 361.79awhp & 384.36lbft! Stock turbocharger delivering the jam!
