Bear with my ignorance here... I am a carguy but a real newby when it comes to all things turbo. Longtime performance nut but I've owned my first turbo for just 4 months now (2000 Viggen, stock I think).
My turbo needle never touches the red zone on the gauge, even under WOT at low or high rpm. Is this a BPV issue? My understanding is it's running as it should, hitting the top of the yellow. But can I get more boost by swapping out the BPV for a manual valve? If I do that, am I in danger of running too much pressure? Bottom line, I wanna have fun, BUT I don't wanna wreck this sweet motor. What's the best route? If manual, how do I know where to set it? Any basics will be appreciated. Thanks!
