Hoosier's were run at 13 cold, around 14 after a pass.

My boost reference is measured at the manifold, so the wastegate and BOV are working fine.

I have a bottle kneck for sure though. I can share HPTuners logs, but I got about 1.5MPH gain going from 14psi to 19-20psi boost. Also I only used a couple more % fuel, so the way I see it, the air's not moving through the engine.

Thanks for the info 98nbmz, i'm going research more on the springs.

Chris, it is a little frustrating. Seems like I "should" have had it a few trips ago.
