fuel press?
i was wondering if i should get an adjustable fuel pressure reg. i am currently running l98 with headers with no cat into slp cat back, accel ignition, airfoil, tb bypass, it is just about stock. i was wondering if it running lean now that is breathing so much better, and has less back pressure?

An AFPR can help you with tuning but you will need a scanner to find out if you are running lean or not.
