MPG help???
I have a 2 door auto with stock 3.73s and 35in KM2s (actually around 34s) and i avg about 10 miles to the gallon. The dash mpg reads 14.5. I have the superchips flashpaq and programed it for the "35s" with the 91 tune on it. It is all city driving and i dont drive erratically or anything and i usually go with the turtle start. Why is my dash mpg off? and why am i getting such poor mpgs?

i dont know how one can expect anything better then 10mpg's with 35's.
i get 12.5 and im almost stock.
wow did some math today after i filled up and im actually getting 13.6 my previous calculations were way off because i was using the fuel gage, witch is also off. The fuel light turned on and i was about a needles worth of space from the red line and there was still 5 galls still in the tank.

If u want more information on amsoil and how to buy at dealer price email me.
You continue to babble about how noone should be suprised to get low mileage with big tires because you get poor mileage stock. Slow down, be easy accelerating, watch your passing and roll on on the highways and prep for hills by speeding up a bit so you dont hunt for gears and rev the motor high while climbing.
I live in fairly hilly country and travel in the woods alot at higher rpms in low gears and still break 20 mpg very regularly.
Oh and btw......I got 350 miles on the last tankful I ran.
