Quick rundown of the setup : On3 twin turbo car, on3 wastegates, dual pump return system with DW 95# injectors, Turbosmart Eboost2 with a 3 port solenoid.
-Turned down the boost controller to gate pressure and it's showing as making roughly 5.5psi on a "6 psi spring"
-Turned the boost controller up to 10 pounds and it pulls hard throughout the rev range.
-Turned the boost controller up to ~11/12 psi and I feel hesitation/oscillation throughout the pull.
My first thought is that I'm running out of wastegate spring as 11/12psi is just about double gate pressure. Tuner says that AFR's/knock and everything else seem fine on his end. is the oscillation/hesitation a normal sign of "boost cut" or should I look elsewhere? I've had a couple people tell me it might be valve float (which I assumed was more of a gen1 problem then gen2), and another recommended upgrading to a 4 port solenoid (I don't have enough knowledge on this to know what difference that would make.)
