So you never identified why it was leaning out, just an indicator on the dyno? I assume that's about when you get into needing a return system to elimiate the fuel pressure drop issue. Now I really can't wait to get my CJM fuel pressure adapter and pressure sender for my multi-gauge. I'm running 10lbs now so it's got to be getting close for me too.

Are you running the fuel pump relay?
