help with vacuum leak

I just replaced my BPV and moved where i tapped into for my boost gauge (was inbetween the manifold and the FPR)to the front of the manifold. what else could cause a vacuum leak and how do i check for it. I do have a VAG-COM and found in block 32 i was getting like -2.4 and +23.4 if that helps at all. also on block 2 i was getting about 2.6 g/f at idle.

Block 032 seems very lean, so it could be a leak

or even just a bad maf sensor.

Is vacuum leak as bad as boost leak? or no difference at all?
