Thread: dic boost gauge only shows half boost

Even though the DIC is a very poor way to diagnose issues related too boost...it still is a pretty easy way to determine that you have a vacuum leak of sorts I'd bet. When was the last time you replaced all of the rubber "T" Fittings around the blower/LIM/BBV/MAP? Or even the Vacuum lines that run from the TB to the EVAP system? Any CEL's?
