Well it seems that I have lost my boost. With my zeitronics read out I'm only showing 7/8 psi of boost where I was getting 15. As I accelerate through 3000 rpms I can hear a growing "woosh" sound but where it's coming from I haven't figured out yet. Wish me luck on my search for the leak.

Like you said you must have a leak some were check all your lines.

Under the intake those lines get hard and brittle good idea to change those for 89 version.
