I have a mustang with almost every bolt on avaliable and I put on a 70mm throttle body. I recently brought the fuel pressure to 44 psi because I thought that I might be running lean. I basically think that I may have went to big. Does anyone have a similiar situation? Mods are: Cold air intake, cobra intake manifold, full exhaust and stock injectors.

yah thats a tad high

42 is probably a better choice, if that makes any difference at all.

Why do you think you were running lean?

you probably dont need any fuel pressure adjustments just yet anyways unless you can hear some detination when youre throwin the coals to her.

Are you kidding me?

well stock pressure is 39lbs how much do you think 5 psi is gonna help? if he doesnt have any detination he doesnt need any fuel pressure adjustments

My car would start then die right away. I bumped the fuel pressure and it stopped doing that. That is why I thought I might be running lean.

have you tried adjusting the idle?

No I actually havent yet. The car would die but wont start right back up. That problem is gone, but I am running low 14's and I should be in the 13's. I am just getting parnaniod that something with the car is screwed up.
