TPIS 90mm TB and Valve cover Breather line I have the TPIS 90mm TB and while hooking it up I noticed it had no vacumn nipple for the breather hose coming off of the Passenger side vavle cover. Do people usually put a plug over the valve cover nipple?

I still haven't figured out what I'm going to do about the valve cover breather since there is no provisions for a vacuum hose on the throttle body.
I do have a catch can but that is something separate for the PCV system.
Unfortunately I have bigger problems now. It seems that the TCS servo is acting up again and I'm only getting 20% pull from my throttle cable. Worse than I had with my stock TB (75% at the TPS). The cam on the TPIS is smaller, I'm going to see if I can swap cams over, but it would be nice to know what the real deal is with the TCS servo and Throttle cables in my car.

You can throw on a non-TCS throttle cable for a quick-fix if you've got a dyno appointment.
As for the PCV, as long as that line connects upstream of the throttle body blade, it will work the same. You can even attatch it to a small filter (it pulls air into the crank case, so you've got to filter the air into it). We normally refer to it as the "Fresh Air Tube".
