hello & thanks for any help or advise on this,
when my my95 wrx hits full boost(1.1bar) it will hold boost steady untill i reach around 5k rpm then it will start to rise & sometimes hit fuel cut.
When on low boost setting 0.7bar it will do exactly the same.
I have no air leaks,no boost leaks & other than this problem the car runs sweet. Any help would be appreciated as i dont know what else to look at to sort this out.

 

anybody???

just after some ideas & suggestions that may be causing my boost to keep riseing & generally been unstable

 

Have you got any form of aftermarket electronic or manual boost controller fitted?

 

fixed it now...had to put my old td04 back on as the td05 had a very loose wastgate penny & wasnt doing its job properly & this was the cause of the boost creep problem. So after trying & exploring every option ive finally got my car running sweet again.....happy
