All of a sudden I can only get my boost to 7psi. I allways ran it at 14psi with my Greddy Profecb. Engine still runs fine. If I punch it fast and let it drop to idle it stalls. If I let it come to idle slowly it idles at 800 and smooth. And no matter what gear or rpm max now is 7psi. All hoses are connected and NO smoke out of the exhuast...
