Help Please!!: Boost Creep problems!

[Cakes]

I am having a problem with boost creep in all gears. I noticed my boost gauge hitting 17 and then creeping all the way to 20. I did a search on "boost creep" and most of the posts were about boost creep AFTER the installation of a THDP which I do not have. Can anyone give me suggestions on where to start and what are the causes and what I can do to fix the problem? Thanks for your time!

Just a guess, but have you checked the vaccum hoses between the wastegate and boost sensor(red) on the PS valve cover?

I took mine off and blew on one end and plugged the other two with my fingers and found the leak.

When you ran the 13.9 what did you have for traction?

I will check the hoses. When I ran a 13.9 I didnt boost on the line. I left completely off idle and just pushed the pedal to the metal. My tires broke loose around 60 feet(2.3 60 foot time)Also I do believe my foot was not competely to the floor since my tranny shifted into OD (yes I did leave shifter in OD) just before the finish line. And Finally it was around 90 degrees with75% humidity so I know all these things killed my car. I am hoping with some boost on the line and the tranny in drive I will be able to get down to low to mid 13s with some decent traction.

Well you have a lot more than I do and my first run I ran 98mph in 90* heat, by my third run I hit 106. Your car should be in the 110 range
