Sorry. Was at work. The picture I posted of my tranny with that silver nipple I was going to mention I don't know of anything that attaches to that. Its just there.
MAP sensor will cause all kinds of weird problems with the car reading boost. The car has to be able to read the barometric pressure outside in the atmosphere to properly know what to do with itself. So check your MAP sensor to make sure its plugged in. Refer to the diagram I posted earlier to find the MAP sensor. Its behind the EVAP canister purge solenoid. One time my vacuum line fell off of my MAP sensor and the car was 'always' building boost and when driving about 50mph it was at 3500rpm. Turns out the vacuum line fell off of the MAP sensor nipple and all I had to do was plug that back in and the car ran fine.
