Cant boost past 14psi

[JMiller]

I just installed a MBC and started turning up the boost, but once i got it to 14psi no matter how much i tighten the thing it wont go past 14. I have it installed with the source coming from the comp. housing and its a ball and spring type. I checked the spring and ball to make sure it wasnt getting caught on anything inside the boost controller. I want to turn it up to 16psi any help would be great.

When is the last time you did a boost leak test?

 

[turboglenn]

A stock turbo especially with the cat installed won't do much more than that anyway, It's probably time for an upgrade.
