Needless to say, I was one of the pioneers of the EGR removal. Shibby Engineering and I developed the first air horn that had high flow and allowed the EGR, or deleted. He shortly later made the true 6.7 air horn. H & S and i worked together to make it code free. I beta tested 86 different versions of code free software. Dealer had a pigeon.

FYI about the olden days. The old man busted his butt for all this
Seems like you have alot of experience! Well I'm glad I live in the great state of TEXAS! No diesel emissions testing except for a couple counties.
