Tuner pro RT

I have a chev 94 1 ton dually. It has a 454, Lunati flat tappet cam (515/530 lift and 218 dur @ 50, headers, Performer manifold, 900 cfm Fast TBI, and small round port heads. I also have an Inovate af meter #3795 LC1. No matter what I do, No matter how many times I erase and reburn the chip the truck does not respond. There is no indication that it is not working it just doesn’t. It says success that it erases and it says the same for the burn but the truck does not respond. I just bought this apu1 kit so it is something I am doing. Please ask what ever questions you need to help me. I have changed the computer to a GM # 1227730
