BroS, here is my situation, last week i was running 7 (STEADY) pounds of booost no problem. No creep or anything it would spool super fast....

now today i adjusted my intercooler raised it a tad and straightend out one of the pipes (hot pipe) and shorted the hose leading to my hks blow off valve...

now i am spooling slower and hitting 10 poundsof boost no problem.....

or is this a problem.....

thx, J

I doubt it's the blow-off valve itself. But it would seem strange that you would get boost creep from doing what you did(assuming you touched nothing else). If you're blow-off valve signal line is connected to the same source as your wastegate line though, make sure you didn't cause a leak by beaking the line or leaving one disconnected. Ths can cause the wastegate to see less boost and cause some creep. Though, I'm not sure what would be causing your slower spool issues. You may want to inspect everything and to a bit of testing to narrow down the cause.
