I have a 2.5" turboback exhaust w/ no cat and no other mods except for a boost controller, and I"m getting boost creep pretty bad. It'll hold at 10, then rise to 16-17 around 4500-5000.

From what I've read, a ported o2 housing or an external wastegate would help the problem.

I'm not sure why mine's creeping so bad. That's one reason (well sound too) that I went w/ 2.5 over 3, bc I thought they didn't creep as bad.

port the wastegate hole bigger and put in a larger flapper. that should get rid of the creep.

34mm Wastegate and port the shit out of everything.

I have pretty much the same setup but 3" exhaust, my 16g has a 34mm flapper & is ported, so there goes that theory.
Creep up the ass.
o2 is not ported though.
holds at 10psi at 50% throttle, anything harder creeps and creeps til i let off. blah.
I think my wg actuator arm might be bad? It's a new turbo with less than 5k miles though.
