Hey everyone, i have an 03 F350 6.0 with little over 300,000 miles. I am having a real bad turbo boost leak, it gets up to about 9psi at highway speeds but then drops back down. I brought it in to the local Ford dealership and had them check for leaks. I was told the issue is coming from my brake hydroboost leaking. Does this sound about right? tried doing some research on it but am coming up empty. Has anyone also had this issue? I’m sure it does need replacement but would it effect the turbo spooling up. And help or explanation would be appreciated
