Boost Leaks
I built a boost leak checker tool and found a rather surprising but unsurprising boost leak on my pickup. The MAP sensor line was leaking at the manifold. Pulled the line off and she was pretty stiff and old. Luckily I had some 1/4" black fuel line and swapped it out. Check the easy things first!!

I'll grab a picture today.
I bought a 4" to 2" fernco coupling from the plumbing isle at Home Depot, a 2" to 1" PVC adapter, a 1" PVC adapter with a 1/2" NPT female thread, a brass 1/2" NPT to 1/4" NPT bushing and then a quick connect air fitting. Screwed it all together and set the regulator on the compressor to 25psi or so. Take the air inlet tube off of the turbo and put the 4" end of the coupling on and tighten the hose clamp. Make sure you use teflon tape around the brass bushing and the air fitting so you don't have an air leak there.
I just hooked up the compressor and then listened for the air leaks. It is really pretty easy to do.
