I'm singin' the over-injected blues!

The spray pattern is why I was saying not to go below 33psi. So far I don't see a lot of conflicting info, your computer can adjust the pulse width somewhat but you'll still run rich until you use a chip or something else to electronically fix this problem. For your N/A combo you'd be better off with 24# injectors, but the 30's can work with electronic tuning.
Set your fuel pressure up to about 33-35psi and give the computer a couple of days to adjust, I think you'll find that it will not be fouling plugs as bad and the better spray pattern will make your motor run better.
