where should i set my fuel pressure regulator w/ 30# injectors

 

I would set it around 40 and then take it on some runs with a scanner to adjust the a/f ratio. Even if you don't tune, the computer will correct most of it to where it wants anyway.

 

Ask Bryan what pressure he tuned it for, if he was using 45lbs. as the basis for the tune and you set it to 40lbs. it won't run right and would be very lean up top. Especially with that MAF those trick the pcm into running lean as is, make sure Bryan knows about that, or better yet put the stocker back on.
