Boost leak

Hey everyone .
Thought I’d share my issue at the moment . Have a 135 e82 n55.
Mods are vrsf charge pipe Wagner down pipe And Wagner fmic evo3
Mhd stage 2+ tune
Car has been great but have noticed a boost leak . Ran the auto logging and found a drop of 2-3 psi according to mhd .
I will be checking lower fmic hose clamps over next few days but all upper connections have been checked and look sound .
When cruising and gears change (dct) you can hear a slight leak
Also when car is parked if you give it a rev at times you can randomly hear the turbo flutter pretty loud .
My question is would it be a loose lower connection of a diverter valve . Heard they can play up .
Any info would be appreciated. Sorry for the long post
