Check out this page, he as a rex and he says he has removed a restrictor for his boost guage? Has anyone else done this and does it make sence to do? "Next, I removed the restrictor from the boost gauge line so it gives faster readings. It may be a little harder on the gauge, but the facotry lamco piece seems to be holding up just fine. If it ever does decide to fail I'll just spring for a nice omori or similar aftermarket gauge. This is what the restrictor looks like - one side has a large opening that tapers down into the pinhole-sized opening you can barely see in the picture." http://www.sounddomain.com/ride/125476/1
I have never heard of this and have no idea why anyone would do it. WTF kind of boost gauge does he have? They are very simple devices.
?? As a FYI, there really shouldn't be any airflow to the boost guage. The gauge is effectively invisible to the vaccum system (unless there is a leak) and if there was air flowing out the sensor, you would know it. The pressure changes induce very little airflow (as the standard 1/8" tubing would support) so I don't think a slow gauge would be due to airflow restrictions. My somewhat incoherent $0.02...
