Looking for better fuel milage

I get what all you guys are saying.....but the absolute most/best you are gonna squeeze out of it with ZERO playtime on the highway for the entire trip is MAYBE 14...MAYBE and that is still pretty shitty mileage for a cross country tour with fuel at $4 PLUS per gallon.

IF it was built to Lobe & thump and sound hot then it prolly is not running at peak efficency, hence really crappy milage...Just sayin not flamin......

my suggestion is just take the tour ( if you have the $$) and forget about the cost....it may be the last one anyone does for a while
