With the mechanical work wrapped up in the shop by Tim, John strapped her down to the rollers for Vlad to perform a custom calibration via HP Tuners. The results? 695.29whp & 746.95lbft on 93 octane! Considering these cars normally baseline between 540-550whp on our dynos, this is right in line with our expectations. Solid outcome and killer value for what we consider to be our Stage-3 performance package for these cars.
