It's only with the kem345 the RCD485 is usually right on within .2 or .3 mpg. I usually get 12.5 - 13.5mpg in 100% city and 16.5 - 18 highway with the RCD485.

Does the KEM310 surge like the 345?

I hand calculated today and got 14.5 and lie-o-meter said 20.8. thats 75% highway and 25% city. does the 310 have the surging that the 345 does?

I have found the 310 to have much better shifting @ light throttle vs 345. 345 flares quite a bit and clunks when it shifts.

I have found out that the touchier the tune, the less accurate the dash is. I know i know it isnt accurate at all when tuned, but i have found tunes with less sensitive throttle are closer related to the dash numbers than ones with sensitive throttle

Im running KEM and as long as i reset the MPG meter its usually within .3-0.5 I have been running the 310 tune since this last Sunday and so far the numbers are accurate. Im getting 15.5-16 mpg's around town. I havent had it for a long trip yet on the hwy but i would assume 1-4 miles better. Im right at 200 miles to a half tank its like 194 n something. cant complain, when the truck was stock i was getting 10.5 MPG those days are long behind me now.
