In towns and around I would "short shift" and try to keep it in the 3200 -3500 range... I was always looking at right at 100 miles before my gas light came on... Past two tanks I shift around 4200 - 4500, and I get an extra 25 miles before the light comes on.
I also got the Rexxer tune for the Remus can today.. I did have a Comp workes cannister and that was what the Rexxer map was initially tuned for ... NICE change! No backfiring, no surging, smooth as glass, and hauls ass... Rode back home and averaged around 80 mph, and it was super. It was H o T too... Temp said it was 89 - 107... engine temp hovered around 205-210...
