Default Car hesitates when building boost help

So here's the deal. My car has been doing this for some time not whole time w I was stage 2, it is stage 2 cobb, and cobb sf intake with 3 inch exhaust and catted dp, when you are in every gear but first, when you are cruising around and the car hesitates when rpms are between 3-4500 rpms, and boost gauge is starting to 0 and up to .5, then if you press gas down whole way it builds boost fine up to 1.1 and doesn't fluctuate holds steady has Subaru factory gauge, the accessport a/f will read up to 18 to 19 when it hesitating and acting up. I saw my turbo inlet was ripped so I changed it with a gimmick, and cleaned maf, plugs have been changed too (when clutch was changed started doing it after this trip to garage) and it still didn't help it. So I'm lost not sure if it's a leak somewhere or not I'm lost. It's an 03 wrx with 83k on it. Anyone have ideas I'd like to know cause I'm out of them. Thanks in advance
