I just have to say THANKS guys for the valuable information provided here-in NASIOC. I've been trying to track down a running rich, low power problem for the last 3 weeks. I was really beginning to think My motor was fubarred! I finally resorted to making up my own boost leak tester and hooked it on an intercooler pipe after the turbo going to my fmic.

Here is the link to what I found including a datalog.

I just bought a 2inch plastic cap from the hardware store. I then drilled a hole and then just threaded in a quick connect fitting for an air line to my compressor. I turned down the air control on my compressor and then hooked up the air line. Then I turned on the valve and kept it on real low. Instantly I could hear air leaking out by my driver side foglight cover. It was pretty loud. Turns out a weld on my fmic let go. It was a crack 4inches long!
