I usually call them if I have questions or concerns. Usually get better service, and you can always reach someone.

Have you tried cleaning the TCV? Might help. I'm unhappy about IPD's lack of response. I have one of their TCV's and could not be happier. I have not delt with them since the ownership change. I'd say give them one more chance before giving up...

I'd say stay away from aftermarket TCVs as I don't they provide much improvement (if any) over a properly working OEM.
