what are you using for a managment harness. If it is the stock harness good luck getting everything to work. If it is the harness from Street and performance you may as well send it back. They were having all kinds of issues getting the car trans to work with their harness. But those trannies are actually pretty good and shift very nice.

I called Street and Performance and they recommended i purchase a harness/ECU elsewhere...The guy on the phone recommended XFI ECU by FAST because if you use a cam or any other alterations the factory computer has too many limitations...so S&P totally rocks for honesty... :headbang: He said the Challenger Vert and the 6.1 GTX owners were dissatisfied with performance and they couldnt get around it due to comp limitations
