[QUOTE="akf250, post: 1545177, member: 2655"] Hello Again Army, Been having fun with the truck. Its been running great on the highway and hauling my truck bed camper with a boat behind it no problem. Temps are great, sounds good, pulls great on hills, etc. But unloaded, I have been having a issue with Abrupt Wide Open Throttle pulls since I completed the build. If I ease into a Wide Open Throttle pull I have 0 issues and the truck pulls hard. If I do a abrupt boosted launch or lets say I have it on the dyno and I am trying to get a number, it falls on its face and runs really rough at 3/4 throttle and on. The motor shakes until I let off the throttle and then everything cleans right back up and I have no problem. What could be causing the issue? A mis-performing injector or HPFP? Reset Adaptive Tables? Trucks got a FASS 165, a brand new stock HPFP, Fuel Bowl ******, and all the injectors were sent to Oregon Injection to get bench tested (stock tips/stock fuel) I ******d the Fuel Cooler but this issue occurs even when fuel is below 70 degrees. I am getting no codes at all and no irregularities in the injector contribution test when revving the engine ( I have not done Wide Open Throttle passes while analyzing a injector contribution test yet) Thoughts?
