When I got the Ultarpower, I could have sent in my transmission control module(TCM) and gotten the shift points adjusted. I decided not to since I felt the transmission was shifting fine. I opted just to have the engine control module(ECM) modified for more towing power. As I said, this was for my 8.1L engine and Allison transmission. It might be different for your Ford but all you have to do is call Jon Brazel and ask.
