Your right, for as far as you go, but like I was trying to say not
everything is a universal law.

You also, have to look at what was going on at the time, 74 ish was the peak
of the oil shortage, and the politics of gas were running the entire show,
so a devise that generated cleaner air, and better mileage was of Biblical
proportions.  What also happened for the first time was the introduction of
unleaded, and the crap additives they used just trying to get the stuff to
run.  i do think it was 76  when GM first used EGRs, and man there was all
kinds of $illy $hit going on.  Things were  SOOO bad that Vegas were selling
like no tomorrow.
