Need turbo help

[Doombreak]

I have a t25 turbo and the car is tuned at 10 psi, the weather has just started to get a little colder and I'm getting boost creep up to around 14psi. I have a boost controller in between intake and WGA and it is not effecting anything. Any help on how to put MBC into effect an hold 10 psi or stop the boost creep.

Remove the turbo and port the turbine and wastegate, run an external wastegate, do the peepers mod to the wga, run a smaller downpipe, etc.

A very short search would have gotten you the info you need.

Is there no a way to do it without going to an external wastegate? Emissions are fairly tough around here and there is barely enough room for what under the hood much less running a dump pipe for the external.

It won't help me cause your profile is not filled. I have no idea if you have an exhaust. When I had an exhaust on my t25 and fp manifold. I was spiking to 20 psi.
10, 12 to 14 psi are within normal parameters on most stock dsm, but every one will defer. Hell, when I just had a greddy type s on my car. It went all the way to 15psi... no boost controller, no exhaust nothing.. all stock except greddy type s.

Those are all individual options, you don't need to do all of them. Smaller downpipe would be the easiest and probably cheapest if you still have your stock one lying around. Or just tune for 14psi, the stock parts can handle that, especially from a T25.

Are you serious? I didn't know that little thing had it in him. I have a 2.5" - 3" downpipe and a 3" exhaust all the way back after that and mine only reaches 14-15psi...

Oh and back on topic: It's fine for the T25 to run at 14psi. But if you want to get it back down and easy way would be to limit the air it recieves. Just like others have said. Smaller exhaust OR you can port the wastegate some to encourage air to not pass the turbine wheel when it opens. You could also check to make sure the wastegate is opening all the way...
