haha.....no no no we all know boost creep can't not be fixed with em however em is a step in the right direction.....still having the same problem with boost creep afterwards port the stock IWG or buy an after market EWG. Thats pretty much all there is to it....

My initial response to the flood of 'search noobie' responses I received was basically "WTF 2 years later they haven't fixed/upgraded this *****!". I'm Glad to see that maybe they have.... I got that 07 ECU reflash about a month ago, still running catless TBE with no other mods. I haven't been able to make it creep once (and I've been trying) since the reflash. |

Giving this thread a good old bump because people still do not understand that boost creep cannot be tuned out.

^^^That's because SOOOOOOOO many people think boost creep and boost spike from lack of tuning/improper tuning of the WGDC are the same thing.
If people would learn the damn difference 98***37; of "I have boost creep" threads would die. ****see below for yet another good example**** Last edited by conker69; 05-08-2007 at 07:36 AM. |

I just thought I would let everyone know that I am running my AP v2.0 now on the stage 2 map on 93 oct and I have now boost creep (at least none that I can notice) and no fuel cut as well. I spike 18psi and tapper off to about 12.
So.................not saying the some kinda tuning will fix your boost creep problems however I am saying tuning can be done to work with it......I know this only from personal experence, however I would still advise anyone to go with some kinda EWG option to further control the issue. Thanks for everyones input on this issue as I know it is something which we all have had issues with along the way. |

well first I really doubt that my boost is to low for boost creep to occur, I'm peaking 18.5 +/- .5 and tapping down to 13 +/- .5 so to say boost is set to a level where boost creep won't happen I can't say that is the case in this situation. Acutally if I had to come to some kinda conclusion from this I would say that boost creep if different from each car even it is the same. Also air temp may have some play in the matter of boost creep. All I know is that my car is running like it was when I bought it from Subaru so I can't say much more than that....... |

To clarify my point I will try and keep this simply, for those who seem to have a 2.5l with any kinda aftermarket TBE and are seeing some kinda boost creep and or fuel cut get, get some kind of engine management. I'm not saying that engine management will resolve and fix all boost creep and or fuel cut issues but it will deffently help in getting you there. Keep in mind that boost creep still remains a mechancial issue which on a stock 2.5l and lead to fuel cut depending on the severity of the boost creep which will be different from car to car. Also keep in mind that a tool such as Cobbs AP tunes for this problem first by raising the fuel cut point from 17.5psi to 23psi. In doing so you will think you have fixed your boost creep however all you have done is "tuned" you car to work with the extra boost that has been created from the boost creep. The Cobbs AP however only tunes from up 18 +/- .5 psi which means boost creeping over that point puts you at risk of running lean and also causing DET. This can be fixed by getting a Protune but you will running you stock turbo at max boost which is not good among many other things and at the same time you still wouldn't have fixed the issue @ hand which is your boost creep. I would still advised anyone to get some kind of EWG option. However their are still several others things becides an EWG which are also listed in the forum. I believe this hits the point that I was going for which is my AP fixed my Fuel Cut however I may or may not still be having boost creep, and my car runs like a million bucks. |

ok since this bears on the topic...if one had boost creep, had the AP to "fix" the problem, and was seeing the same results as jeremy05sti but wanted to be extra safe, what exactly would be involved in going the external route? And what are the best products for the money?

and this can go on and on, so not to draw this out any further lets just leave it as it may.
I'm simply letting whoever feels like reading this know what I have experienced from a first hand basis. I'm not saying I'm right or wrong just explaining what I have personal dealt with. Btw my cars FEELS even better now with a ProTune. So now please let us hear what Mr. Negative has to say now....... |

Im thinking of going to a stage 2 setup, but having had turbo cars in the past, im very familiar with creeping issues when removing cats. I was just wondering if anyone here is running the MadDad V2 one piece downpipe (catted) and still experienceing boost creep.

Hi, I have a Subaru STI S202. It is the limited edition Japanese spec STi that comes with 320hp. I recently bought a few components to make her a little faster in the 1/4 mile. I just bought the 3" Cusco Catless Stainless Steel downpipe. I was planning on taking off the rest of the exhaust when I race and putting it back on for the street. I have an Autronic engine management system, but wanted to know if I will have to worry about boost creep? The problem is the mid pipe has a cat so it will restrict. I was going to make a catless midpipe, but we don't have any flanges down here as I live in the Caribbean, and we have a big race coming up this weekend. Any info would be appreciated. Thanks Special |

Well to answer your question in short Special, Its hard to tell weither or not you will experence any issues. Since all cars are different some may experence problems with just an aftermarket DP whereas other won't have any problems until they use an aftermarket catless TBE. You'll just have to experence it yourself which in this case shouldn't be to much of a problem. But with your STI I'm not sure if you IWG is any different. I'm sure it is seeing that you probably have a VF34 So try it out and see what happens..... |

I know this thread has been primarily focused on the STIs. But allow me to interject with a question about my 06 wrx.
Will a regular wrx suffer boost creep with a Cobb Catted DP, and a Prodrive 2.5 inch muffler ( same diameter as stock) Generally speaking, are the regular WRX's less prone to the creep, I'd ideally like to be at stage 2 without having to worry about taking apart my car to port the wastegate on the turbo. |

If I'm running Cobb AP HF Catted DP with a full tbe, and COBB AP protune, what are normal turbo levels, just so I know what to look for when I'm cruising, and what levels to recognize a creep or a spike

I have no idea, if it's protuned then ask your tuner, he's the one who set the boost. Isn't that just common sense?

Yeah I guess it is.
How far off normal boost levels should make you concerned. |
