While we are removing EGR items,
I have been told that the Aluminum unit under the air cleaner housing
(looks like some type of Air Flow meter on a SDL)
seems to be very restrictive -
and that it's only purpose in life is to adjust the EGR valve to match incoming air???

is this correct and if so, how about offering a "level 2" EGR kit
with the necessary plumbing to eliminate the Air flow meter completely
and plug the vacuum lines, etc......
