Boost is stuck at 12?

[JKGeorge1116]

I just recently bought an 87 regal t type, this being my first turbo car im a bit new to all this. I was attempting to turn down the boost. when i bought it it was set to about 25 pounds of boost and the car is pretty has pretty much stock internals. It has alky injection. Well once i turned the boost down i got it to about 10 pounds. but when i tried adjusting it higher it hasn't really responded. i have it set on max boost at the moment and I'm getting just about 13 pounds of boost. Anyone have any idea whats going on?

Honestly, we need a little more information.

Does your car have the stock wastegate actuator solenoid hooked up and plumbed like stock?

Does your car have an external wastegate with a manual boost controller?

When you say you have the boost turned up all the way, how did you turn it up?
One thing that might help would be if you could snap a couple of digital pics of your turbo and the actuator, as well as motor shots, and post them up here. We would definitely be able to help figure it out.

We're all here to help.
Looks like the others are helping out in the Engine Tech forum.
