Default Stage 2 only giving me 16 psi on my 05 STi

I've had stage 2 on my car for well over a year now and never had an issue. Well yesterday my car was seeing only 16psi when it usually sees about 17.5-18. And today I'm seeing the same thing, mind you it's a little warmer out then the common 40-60 degree weather, it's around 75. I have a new turboxs Stealthback and Cobb SF intake. I have reset the ECU today and am going to see if this helps. Any ideas? Anyone else's car acting this way?

Does anyone think the stock axle back may be affecting boost pressure? Heat soak from DP? All attributing factos maybe. I haven't tried the HWG map yet. May just give it a whirl this weekend. Also My boost gauge is showing a little more vacuum then normal. Signs of a boost leak maybe? I don't know guys, just so much crap to look at and am actually wondering if their are others out there experiencing the same or has experienced the same issue. Any help would be great though guys. Thanks.
