My BOV leaks under boost part throttle and when I return back to full throttle... why?! It happened every power pull I've done with people, I attributed it to low traction when I start letting off and getting back on the throttle, but tonight when I went out attempting to tune, it appears to leak boost most of the time under heavy/full throttle. It's really dumb.
HOW FIX?!
Current ideas:- torque the adjustment bolt down so the spring is under severe tension, however it probably won't open at all unless i'm in high boost (which means surge when i let off at low speeds)
- take apart bov and examine diaphragm quality
