Bummer.
Well, I'll start with the tables Kfred provided me and tweak from there. I compared my stock files to the file I posted and the tuner did adjust the Boundary and EOIT in one of the Normal tables (can't recall if it's EOT or RPM and I'm at work so I can't check my tune files). So there was some work done to it but probably not as much as there could be to get it as close to 100% as possible.
I'll tweak what I can and report back with the results. I'll monitor my instant fuel economy on the same, flat, stretch of highway to see if I can eek out anymore fuel economy down low in the RPM band.
Still having trouble correlating the spreadsheet values to how Kfred got his values, I think I just need to sit down with the spreadsheet on one monitor and my tables on another with a coffee in hand and let it soak in for a bit.
