I recentlly installed a boost gauge and I notice that even uner WOT i never go past 0-1 psi of preassure. I get the expected 20 psi vacum at idle at vacume varies from 0 to 25 psi vacum when driving. I checked the boost hose to make sure tere were no leaks and that it was hooked up correctly. At this point Im assuming that I have a boost leak somewhere. What is the best method for tracking down this leak. Anyone have a usual suspects hose list?

 

Yeah I insatalled the gauge last night cuz im planning to hit the track friday and I wanted to make sure it was running properly. I havnt had a chance to check the connections yet. I guess ill check the manifolds to turbos when i get home. which is what i am hoping is leaking cuz it should be easier to find and fix.

 

Found a huge (1/8 - 1/4 inch diameter)hole in my coupler next to the intake manifold in the piping that leads into the intercooler. Appears the damage was done from rubbing.
