boost fluttering **SOLVED**
Just installed my freshly rebuilt engine and now I have a strange boost flutter. It starts at around 10-12 psi and just shutters real hard and doesn't really climb up on boost. The shuttering is pretty violent, enough to shake the car. I thought maybe it was wastegate related, so I unhooked the gate and ran it with just the spring pressure...no change. O2's read in the 850 range when it happens. Wondering if it could be electrical, like coil pack?? Or maybe fuel pressure regulator??? All hoses look good too.
