Boost dropping when hot
Hey guys I have a 1990 FC 13bt and I'm running my boost at 10psi. The other week it started to drop Down to 5psi when hot and would stay like that till it cooled all the way down.. Any ideas as to what could be causing this?
Luke.

when its hot, stuff start to expand, could be a small rip in the couplings, or maybe vaccum lines.
