Default Got my car back, turbos are back in and are happy, well, sorta there is a major boost leak somewhere

I got the car back and had the MBC turned down to 7lb for 100 miles or so just to let turbos break in (no zero clearance rebuilt k16). I the negative boost deviation error code but did not think much of, and cleared it. I turned up the boost a little, and noticed I am not going much past 10lb, and it takes forever for boost to build. checked codes again and negative boost deviation. Checked all the hoses and noticed that all the clamps could use some tightening. I reclamped and tightened down all the fmic connections along with the TBB and BPV's. Did a log of 115, and noticed I have a 400-450 mbar leak (difference between requested and actual) accross the spectrum and boost builds up reeeeaaaal slow. I don't hear the boost leak, and the only air lines I can think of are from the turbo to the FMIC. Can anything else cause such a big leak? the bad thing is I won't be home in three days otherwise I would slap my trusty pressure tester on the intake.

And BTW, there are no more grommets to worry about, I had a line fitted on to the elbow of the y-pipe to eliminate that. The installer went to temporaryliy put in the accordian hose with the grommet fitting and almost snapped the grommet back into the y-pipe. Yikes!
