boost cutting
For some reason when my car hits peak boost the boost will then drop to 16 psi and slowly climb back up. This causes the car to go lean and also feels extremely slow. Im thinking that the wastegate is opening prematurely or something because I cant find any boost leaks and my fuel isnt the problem. I have another wastegate so I can just exchange them ad see if this fixes the problem. DO you gys have any other suggestions to check for?

yes i did. Its not that. Its my boost controller. I unhooked it and my boost doesnt cut anymore and of course goes way past 25 pounds so i have to let off but before it wouldnt even hit 20 psi so I know this is what it is.
I am just not sure if the vacuum line is torn or if the boost controller went bad. Does anyone know where to get a replacement vacuum line and how to check if the boost controller is working properly

old school boost controllers are bleeder valves, its like a controlled boost leak.
hallman pro is good. Ive had mine hang up before tho inside. to check just open it up and make sure the ball is not wedged inside the spring. be sure to do this inside (your house) so you dont lose the ball or spring, the ***** very very small.
