I hope I will have the opportunity to take another long road trip from Denver to Crestone. I got 51mpg on B100 with the EGR defeated. I may go again in late summer; if I do, I will re-connect the EGR and compare.

I don't particularly like the MAF twist method either for those reasons. Although, for quick testing purposes it may be helpful. Did you incorporate a temperature dependent On-Off to your EGR delete? Are you noticing an increase in engine responsiveness from the EGR delete?
