06 mkv gti fsi. only mod is a neuspeed intake. at about 2200 rpm my boost drops off quite a bit, then at about 2400 rpm it comes back < that is steady and happens about 90% of the time when giving a little gas. also randomly i will hear woosh noises while building boost, and when that happens i feel boost drop off too (its not the intake, i know what that sounds like) and sometimes i accually hear the DV "blow off" before i let off the gas ... you guys think maybe a boost leak and if so where from... DV shot? maybe pinhole or ripped diaphram? kinda has me stumped. the issue started before installing the intake while it was 100% stock. lmk what you guys think. thanks!!
