You ET isn't really that far off, but the MPH is showing that you're down a little on top end HP. The 1" space might account for some of it too though but I think I'd try some larger injectors.
Just some 'been there, done that'.

I have more then enough fuel now. My pressure is only at 40, and my et drop with a increase in pressure. My car is damn fast for what I have done, it a full weighted car, with just Gt-40 heads, and stock cam, stock intake, stock bottom end with 128k on it. Try taking a car and doing that and running a 12 with it. That is a great mph for the mods. Once I put my cam and intake on it should be done in the low 12's. Just a thought to give you more info on my combo.
