Ok, I think the problem is the BOV may be leaking?? But this is what its doing: At idle there are no apparent issues, start driving and its fine, shift at low to regular rpm's and everything seems ok. But as soon as you start getting on it and shift the BOV makes its noise but seems to "whistle" out until the noise goes away. Seems to me like the valve is opening but takes a while to close back up....or maybe not reseating at all???? LMK, if anyone has any ideas on this? Could I need to replace the springs inside? Am I loosing power because of this? (it seems to be running strong)
