Sounds like that should do it. I somehow missed you had posted boost readings or I wouldn't have gone on about the BCS (wherein you would have seen the 7 PSI).
Bummer about the bolts. You should grab some PB blaster and always pre-soak stuff like that. You really need to get a heat shield back on there as tempting as it is going to be to leave it off (and don't leave it rattling or it may bug your knock sensor).
