..................................28.8............ ..28.0 **
..................................28.7............ ..29.5
..................................28.8 ..............29.4...............29.0 mpg

(sorry about the odd table format - got to be abetter way- but I don't know it )

A-B-A average 29.3 mpg with vs. 28.0 mpg without

* scan gage was reset 0.2 miles into course due to possible semi interference, so this run is .2 miles shorter
** I may have punched it too hard on acceleration - the ECU seems to stay in a higher performance/ lower FE mode for ~90 seconds or so after +50TPS - My bad - not very Hypermiler like. very noticable loses in real time at beginning of course - not too much difference in the averages over the course.

Variances noted, but all data is used in findings
