With the mechanical work wrapped up in the shop by Alex, Matt strapped her down to the rollers for Vlad to perform a custom calibration via HP Tuners
. With 93 octane in the tank, Vlad increased the 5.7L's output to 427.71whp & 418.74lbft! With an initial baseline of 360.07whp & 393.16, this '18 Challenger R/T got a nice jump in power that Jim is sure to enjoy!
