We weren't able to get over 25psi with the wastegate spring all the way in, and the boost controller wide open. I need to know possible causes for this problem.

1) Jarrett says that the spring on the wastegate can easily make 30+ psi of boost.

2) The car made 18psi on the wastegate spring with it backed all the way out before the boost controller was connected properly.

3) Now the car makes minumun about 14psi and max 25.5psi.

Haven't tried it with the BC off again yet, but Jarrett says it should be 18psi like that.

Suggestions welcome.

How is it possible for you to run less (14 psi) with the boost controller hooked up than the wastegate spring (18 psi) alone? It sounds like the the controller is not hooked up correctly.

I think problem solved. I think the boost controller just didn't memorize the settings on the dyno, because tonight on the street I hit 29psi like nothing.

What kind of Boost Controller do you have? I know the Profec B Spec 1 will not pass around 25psi.
