stock boost gauge or aftermarket?

That is what is called "compressor surge", not boost creep.SaiyanFury said:Boost creep can also result from low performing cams from my research. If your turbo is pushing too much air, but the engine can't do anything with it, you might simply have too much boost. Just a thought. Cams can address this problem. It's not a fix, but perhaps a possible solution.
Dasamary said:Boost Creep occurs due to a too restrictive exhaust. Ive never had boost creep on the stock exhaust and when I went with a 3" catback no issues as well. Most boost creep on 16G turbos occurs due to the 02 housing being too narrow for the amount of exhaust the turbo is trying to push through.
I used to run an APEXI BOV vented to the atmosphere and it wouldn't hold boost because I didn't have the washer tightened. The BOV was trying to vent when I hit 13 psi. It felt exactly like fuel cut.
I would seriously doubt a T-25 would ever boost creep...unless you put a stock honda pencil exhaust on your car.
Please search "boost creep" before posting, smaller exhaust reduces the chance for creep. And yes though rare, T25 can creep.Boost Creep occurs due to a too restrictive exhaust.

Boost creep has little to do with an O2 dump, more to do with the poorly wastegate path flow design in the turbine housing. Proper porting of the turbine housing will resolve boost creep without having to dump in most cases.I have a feeling that the T-25 can't make enough power to really create many boost creep problems. The more power = more exhaust gas. More exhaust gas will cause you to boost creep if you can't divert it away. A good Wastegate with allow that as will an atmospheric dump.
