How well is the factory solenoid working with the external wastegate? I thought I remember reading somewhere that right now there is some overboost happening when boost is below the wastegate spring psi, but workingly properly at higher psi. Is this correct? Any progress on being able to control the solenoid properly all throughout the psi range?
