got a 05 cummins 48re muldoons fmvb 1000hp trans, s&s 100% sac injectors, S&S 12mm cp3, fass 290 stock turbo. ive got issues where my truck will surge hard when accelerating a bit between 1300-2000 rpm. the frp fluctuates between 13000 and 17000 psi during that time. this issue happens mostly when i have the tc unlocked. sometimes when this surging gets real bad, i can let off the throttle and the truck will continue accelerating while surging untill 2000rpm or i downshift. ive got the attached log and tune files.
another thing id like to figure out is how to get the reverse lights and prnd21 lights to work. Park light goes on when im in park or nuteral but id like all the lights to work correctly. id like the reverse lights to work so that i dont have issues with people not seeing that i want to back up etc.
thanks
