I would expect that it was protuned anywhere from the 14psi to 20psi range. Just give your tuner a call and find out what it's mapped for.

creep question
I am going to post this here, because it has to do kind of with boost creep(Sorry if it does not belong here). So i know boost creep = bad and read all about it. I have a wrx not an sti (2007) I was going to just get a cat back to avoid boost creep all together. So i am skimming daddysscp website and i came across the MadDad(TM) Metal V2 two-piece Downpipe, I have seen this b4 nothing new but reading a lil bit more i read "The MadDad(TM) Metal V2 is the only hi-flow catted downpipe with a catless wastegate design, offering the fastest boost control response to eliminate boost creep." My big question is is that true? if i get this down pipe i will not have boost creep at all?

I had mine tuned and then re-tuned several times. I couldn't keep boost under 20psi when I accelerated. Yesterday I had my wastegate ported and now it stays at 17psi and the car feels like a beast. I didn't check incorrect orifice size on the boost control lines, stuck/siezed wastegate, etc etc., but I do know that porting the wg fixed my problem.

If I'm running an axleback and no other mods, would boost creep be an issue?

Mate Please read this whole forum.....the answer is here.....Also read nhluhr above post.....

Just so I understand boost creep occurs at high RPM's and if your tune is pusing ~20psi between 3-4kRPM (stage 2) it's just a boost spike?

You should know your target boost, and compare it with what you're hitting. You can log it or get a boost gauge, or do both.

And hopefully your tuner hasn't set the fuel cut so damn high that it is useless...

Thanks For All The Info. All This Was A Big Help, Especially Being A Newbie. I Just Got My Sti And Obviously I Dont Want To Have Any Problems With It. This Definitely Helped Me Make A More Wise Choice Getting A Tbe Or Cbe. Thanks Guys, Keep Up The Good Info.

I read most of the thread and it seemed mostly to pertain to STi's.
I have a 07 wrx with a turbo xs TBE that i bought and installed without knowing i needed to do anything else (im a newbie). anyways, ive been experiencing the stutter refered to in the first post and i just feel like im breaking my car. Ive been told getting the cobb stage 2 AP with eliminate this problem, but i dont have the 700 dollars right now since im in college. besides getting the AP, is there any short term solution like reinstalling my stock axel back? ive only had the TBE on for about 1000 miles, but could someone shine light on just how much damage i am doing to my car by keeping it on till christmas time? Thanks in advance, i know i probably sound retarded but this is my first turbo car and im not all that mechanically inclined to begin with. |

If you hae a TBE without engine management, you're most certainly hitting fuel cut, as it's like 13 PSI on the stock map.
You need some engine management. Period. |

Does someone have step by step direction for this? What tools were used? My friend and I might attempt this today as I have a divorced wastegate DP going on.
