    Small surges in rpm when accelerating WOT mainly

    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.

    Tune is useless. Log is needed. Maybe your trott,e closes.

    I loaded a log if you have a chance to look at it and let me know if you see anything that would be great. Thanks

    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.

    would that be the Maximum Flywheel torque that I adjust those settings under?
