Got my new setup last week finally finished car was tuned for 30 psi today finally got on it ,and it only boosted to 24 to 25psi thae same thing happened to me a few months back and i had the buschur old style controller and it backed out do u guys think this happened again or its something else....what boost controller is good and hold boost well too....thanks..

 

I have a Hallman Pro
Has worked perfect for me, tuned to 25.5 psi.
MAP Performance has an awesome price for them too!

 

Possibly boost leak. Do a test.
