Well pretty much what the title says. Under what conditions force the solenoid to keep the bypass open? I keep having an issue where if the car does go into boost (05'GTP) then the pressure will drop back to 0. Even downshifting it will not go into boost for less than a second. I have noticed that sometimes I will ease into it and see 2-3 psi then I'll push it a little more and get it to 7-8, then it just drops to 0 and I can slow and punch it and it runs like it's NA and the gauge won't go past 0.

Thanks.
