Hey folks, I've been having some issues with my ProCharged GT. I took my car to a shop a little while back to have 3.90's and a NX Ntercooler spray bar installed and when I got it back and drove it for a bit, I noticed the bypass valve was no longer discharging like it used to. I don't think the shop that worked on it had anything to do with the problems, so I'm not placing blame, just wanted to mention the mods I had done. The problem I seem to be having is that the valve isn't closing when I get on the throttle, not even at WOT. What can cause this issue? When I let off the throttle after going WOT, it takes a while for the RPM's to come down, there doesn't seem to be any snap, whereas there used to be a very loud blast of air from the valve before.
Any help would be great.

Thanks,
Kris Horton
