Thanks Dave!
If any of the seasoned members can remember Tygen1 from several years back, you will probably remember that he was as crazy and dedicated as I am. I recently got in contact with him. I found out that he is no longer in the Eco-game, but he is helping me out in many ways.
The biggest thing he is doing to help me is he is giving me his lean burn module that helped him get such high mileage!
Ty said that at 50 mph, in lean burn mode his instant readout was around the low 70s.
Watch out, I'm soon to be an Prius/Mirage/Insight-buster
