My car has been down for the better part of a few years and everything is finally back up to where it should be, almost. This time around I went with the DM IC kit and got a genuine Tial BOV with it. When I first started the car it wouldn't idle AT ALL. I swapped the standard 6psi spring to the 12psi spring that is in there now (which is what Tial claims will work for 20in vaccuum) and it still just sits there and idle surges from 750 up to 1100.

As soon as I disconnect the vaccuum line and plug it the car runs and idles perfectly. No issues at all, no codes to speak of. But as soon as I plug it in to the Tial, it won't idle right.

I still have the 6psi spring that I could also put in the valve, but I hesitate to do that and don't want to have compressor surge later on.

What spring are you all using with the Tial to get it to idle right on the 7M? Any ideas on what else I can to do make it work?

Thanks
