I have a 18 Trackhawk we done quite a bit of work to paid a tuner to do a remote session on dyno and we still have some quirks in the truck i need to work out after doing a little street driving. The tuner seems to be way too busy to help us anytime soon and i really want to smooth these issues out, first off it has a pretty good part throttle surge. I've toyed with the throttle settings from some research here and its tremendously helped that truck drives 100x better but I am a Veteran gm tuner this mopar stuffs new to me and i could use some insight. My other issue is a extreme timing pull going into 5-6 gears on a pull torque source goes from pedal to transmission. I will attach the final tune file from tuner and the one where ive been tweaking it along with some logs. Any helps greatly appreciated. Truck made 950 at the rear tires on my dyno with front shaft removed.e85 v4.hpt2018 Trackhawk JP V3.hptv3pulls.hpllight throttle surge.hpl
