Here's my problem. i just installed a manual boost controller and been slowly turning it up to get up to 11 psi. now that i have it set the boost will go up to 11 and then it drops off to 5 or 6 psi which is where i was before i installed the controller. i checked for boost leaks i didnt notice any. thanks in advance for any help.
Check your BOV. Tighten it down if have a way to. I was having that problem with my talon and I tightened down the adjuster on the top and it helped. YOu sure you got the controller hooked up right? Should go from your boost source to the controller to the wastegate.
