With the mechanical work wrapped up by Dylan in the shop, John strapped her down to the rollers for Vlad to perform a custom calibration via COBB Tuning's Accessport V3. With 93 octane in the tank, Vlad increased the EJ257's output to 385.32awhp & 358.11lbft, and after switching to E85, output jumped to 403.24awhp & 410.14lbft! Nice square setup with usable power all over the rev range!
