I haven't had time to put my new bushing in & play with it yet. Need more boost!
I'm pretty sure I have the 14psi spring it shipped with.

Nice. I'm sure the stock manifold helps a bit, but the FMIC might even it back out. Avcs? Single or dual? What AFR/TIMING/AVCS @3.6k? What do you start pull at? I start at 2500.
