Boost leaking from MAF !!
I was doing a boost leak test for my A&A supercharger piping and I found a small leak in the MAF, is it normal ? !!

Yea and sooner or later with enough boost this is what will happen..This was at 16 psi and I was back peddling off and on outa boost in 3rd gear grabbing for traction on the freeway and kaboom sounded like a bomb going off. The A&A MAF girdle fixed that from ever happening again, but the guy that bought my car back peddled and kaboom again and the weak point this time was back of intake blowing a hole in it.
Just putting a girdle on it tho wont help you cause its already coming apart/leaking, you probably need to pull MAF halves apart and re glue/seal them then girdle it cause the halves are coming apart already. MAF girdle all by itself tho might seal it back.

Seems pretty minor coming form the connector area. If you install a new MAF pressure test it too and add the MAF girdle or delete MAF altogether and tune it Speed Density while adding a 2 bar map sensor.
