Delayed shift when 50% or more throttle??
Has anyone else experienced the shift delay due to the TCM being off once the jeep has been lifted or supercharged?

Had issues with my daughters after the dealer decided to flash her ECM while it was in for an oil change. Jeep had a superchip loaded for gear and tire size change in it at the time and it never shifted the same, Dealer would not rectify the problem. So I contacted Mike at OST Dyno as a friend gave me his info and he was able to fix the issue. It did take a second flash to get it exact but it shifts perfect with 40's.
