boost creep.. its possible, but boost creep does not feel the same as the way you are explaining it.
especially since you said it happened when you originally got the car.

Well if you are hitting .14MPa that is crazy high on a stock turbo with no supporting mods.
BTW maybe this can help you:

My experience with boost creep was on a cold morning/day. I threw a CEL + Flashing Cruise light. I basically hit the ECU limit which then cut fuel and the car did a violent kick.
Q) How do I know if I have boost creep?
A) If you have a full TBE, then you probably have it. A boost gauge will tell you what pressure you are at as well. Fuel cut occurs when the ECU senses boost in excess of 17.5psi for 2-3s. Fuel cut in my experience is a very violent "stutter" from the engine that resembles extreme knock, followed by CEL.

So how so you remedy the problem? I just installed my Cobb dp on my 2012 wrx I have 7600 miles and tonight I was on a back road and wanted to try out my new stage 2 tune so I did a wot run. In 4th gear at about 100 car kicks hard and stops. Flashing cruise control, traction and cel pop up. Can I just clear it or do I need to replace something? Mod list is as follows:
AEM CAI
INVIDIA q300 cat back
Cobb catted dp
Cobb ap stage 2
AEM CAI
INVIDIA q300 cat back
Cobb catted dp
Cobb ap stage 2
