Quick boost creep question

[NyQuiL07]

So im picking up a thermal catback, ahp test pipe and downpipe tomorow and plan on installing it a day or so later. Ive also ordered a o2 dump off ebay, that should arrive in a week or so. Ive read that im probably going to start creeping on the t25 once the exhaust setup goes on (coupled with my other mods of course, which are in the profile). My q is, i want to install the exhaust setup before the dump gets here. Is it definite that ill creep?, also would a turboxs mbc help relive the creep before the dump gets here?

You're likely to creep with that setup, but putting the MBC on and dialing it down should definitely help.

If it helps at all to know, I have 2.5dp, 3"cat and 3"cat back with a MBC and i still creep up to 3 psi max. Also I have no porting done whatsoever on current setup. Not bad, but it still creeps a bit. Im in at 15 psi, but it creeps to 18 psi max.

if you have a cat and an o2 dump you prolly wont creep....
