Default fuel pressure question for 93-95 cobra owners

Just finished installing afr 165s on my car, and I was wondering what I should have the fuel pressure set at with the vacuum line off. Rest of my mods are listed in my signature. Also, I know onyx cobra and a few others have put afrs on their car, did it run like garbage till you got the tune? On my 94 gt i had afr 165s and a e303 and it ran fine before the tune, but my cobra is running like crap.

With stock fuel injectors I believe it supposed to be at around 30 psi or so.
