it's probably not "glued" in. The coupling is made from silicone so it is more then likely a very tight fit getting it in there. If you want to shorten up that metal tube take some tooth picks and slide them down between the coupling and the metal tube and then shoot some Windex there. wait a couple of minutes and you should be able to turn it and pull it out.

what is the elevation where you drive the car?

Does it hold 18 psi or does it hit 18 and then drop back to 15 or 16?

OK you have a tune then. I don't think it is the GMPP tune as that would require different MAP and TMAP sensors. It is more then likely a Trifecta tune. If you e-mail them your VIN number they might be able to look it up to see if they are the ones that tuned it.
