So Ive got a 850, Ive hooked up a boost controller, I believe correctly. And Ive unhooked everything from the lil sensor or w/e it is on the air intake case. I did this cuase its what one person said to do get rid of the 5psi max on the turbo. Did it and im still only getting 5psi. And I do believe Ive ajusted the boost controller enough. Because I can here it letting off the excess while Im speeding up, if I unwind the controller it does not do that. So how do I get rid of the blocker? Its starting to **** me off.

 

You should be able to hit atleast 15 with it (I wouldn't run that all the time)

He is how you can test to see if it is the MBC. Remove the hose off the waste gate then take for a small quick drive. You should be close to 15 PSI. If so then something is wrong with the MBC or the way you have it hooked up.

If you only hit 5 psi then you might have other problems.
