Looking for some help... This is a friend of mines car. 2018 Charger, 6.4, E85, 2.9 Whipple, Forged Internals, Dual Pumps, 1 Piece Aluminum Driveshaft. Everything else is stock. Few weeks back everything was fine, running pump gas, went racing, during a pass on the top end car started busting up. Thought the BAP went out and fried the fuel pump. So he upgraded the fuel system and went to E85. Car runs fine, normal driving is fine, WOT pulls and the car starts bucking. Car will randomly cut off as well. No codes. Tuner can’t see anything on the logs. Pressure tested the bypass and holds the pressure no problem.
