I am going to preach again. People need to Search. its not that hard and odds are you are not the first person with this problem/idea and its already been talked about.
But on a different note here is a brief explanation by 95GSXracer on what boost creep is. "I cant get the www.racingknowledge.org website to work here at work, but I believe there is a sticky about WGs and boost controllers that may also explain creep. The very short version is that its when your WG cant bypass enough exhaust around the turbine wheel to accurately control bost. The result is it will hold set boost until some rpm where it will start to rise on its own and continue doing so until you let off. As an example, my 14b with 2.5" BR turbo back (test pipe) would hold 18 psi to about 5500 rm, then it would rise to 22 psi by 7k. "
and if you want to know how to cure the problem you can start by porting out you o2 housing. check www.vfaq.com , you can also do a search because once again it has been discussed before. hope that helps. :thumbsup:

Cant blame him for asking poeple to search. There are questions that I answer every day. Its like going to work, or taking a shit. You just know you are going to have to do it. Boost control issues, trying to swap a 4g63 into a NT, etc. I have a folder with about 50 text files where I copy my long, frequent replies so I can cut and paste when it gets asked over and over again.... :)
But in your defense, I know there is a TON of msinformation out there. Go to a forum and ask what boost creep is. If 20 people answer, one will have it right. ;)
95_GSX did a good job giving the short version. I believe that sticky on RKO does explain it well. If you still have specific quesitons after reading it, let us know.
