I just upgraded from bone stock ct to a gt35r, and i have an HKS SSQV. before the upgrade, the BOV would make all the noises expected, like that high pitched noise we are all familiar with. NOW with the gt35r, it makes a new noise, kinda like its not even opening. when i boost hard and let off, it doesnt make the high pitched noise, it just makes a huge woosh sound (which may be normal, but ive never heard it before). i actually think its compressor surge. i have vac at the BOV line. also, with my car idling, if i rev it up and look in the BOV where the valve is, i can see the valve move when i let of the throttle. any ideas?
