Installed my 2 stage diablo chip yesturday, truck starts and runs fine with 93 gas. Question is; when I switch the switch to performance tune with truck off and restart truck, the truck runs fine. I just don't feel any difference in the way the truck drives. I don't feel like theirs more power and trans shifts the same as stock. I've read the diablo instructions a least 3 time to make sure I didn't over-look anything. What should I do?
The center position is the performance position. The setting opposite the notch is stock. You can't start it in stock and switch over to performance (it will stay in stock). You can only switch between 2-3 (and you don't have three so it will stay in 2 if you try this). Start it in the center position and give it up to 100 miles and a few key cycles, it gets better as the Ford computer is adaptive.
