Steve brought his 2018 Jeep Grand Cherokee Trackhawk in from Maryland for the first round of modifications! Up first, Archer set the supercharged 6.2L Hemi up with a Metco 2.85" upper pulley, Metco billet idler, Stainless Works long-tube headers connected to the OEM exhaust system, Injector Dynamics ID1050X fuel injectors, all topped off with a JLT Performance air-intake system. Once the mechanical work wrapped in the shop, Charlie strapped her down to the rollers for Vlad to perform a custom calibration via HP Tuners.
The results? 762.63awhp & 683.96lbft on 93 octane! Our opinion on these things hasn't changed: this is the ultimate daily driver.
