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 ~15psi, Vlad increased the LT1's output to 782.50whp & 666.11lbft! We can't help but wonder what she'd do with a bit more boost and E50 in the tank...
