boost creeps up as rpm's rise ??

[PsSsShTGSX]

if i step on it in 2nd gear at about 3k, my boost will spike to about 15 and then hold at 13-14all the way to redline.then i tried it again from a 3rd gear roll and my car spiked to 15, but now dropped to about 12psi and it rose with the rpms( to 14psi.) i know that the t25 is crap and it starts to run out of steam at 5k, but mine is doin the opposite!!! its goin up with the rpms. i have an hks exhaust, stock cat and downpipe. i plan on gettin an apex downpipe in the very near future. Ive been told its because i dont have enough exhaust flow, thus im having a creep issue. so i would want to get a downpipe, and port my o2, correct?

My t25 creeps from 13 psi to 15 psi then drops after 5500rpms. Basically have to port out the wastegate and o2 housing but who cares, I get 1 count or no knock at 15 psi with my t25...

Correct me if I'm wrong (which I probably am ) but doesn't boost creep occur when the exhaust flow is too good (like if you put on a new DP)? Porting your WG and o2 housing will probably eliminate it, but I think the DP will make it worse. Now if you port the WG and O2 housing, AND buy the DP, you should be okay.

^^^^ You are right. This is a very minor case of creep. Mine creeps to 20 and cuts.

I creep to 21-22psi and hit fuel cut because of my exhaust.
