I have a 15 Charger RT 5.7 R&T Mods are long tube headers 1 7/8, no cats, mmx NA lope Hpt+ cam, jlt CAI, 85mm TB, FIC 525h injectors. When driving say 3-4 gear and if I give it WOT @say 2500rpm I feel small power surges as rpms go up. I uploaded the current tune on the car its not a stock tune i need to change that. If anyone can look at it and tell me if they see anything that would make it do that and how to fix I would appreciate it.
Looks like your torque converter is having difficulty negotiating the difference in engine torque without the torque model updated. It's attempting to slip/lock and the pressure profile isn't right for the new torque so you end up feeling it. Take your dyno sheet and rough in some estimates to the torque model.
