KEM 310 MPG's????

4tonGT40 · Oct 22, 2011

Im running KEM 310 as my DD and although i know the onboard MPG display is off sometimes, im showing 18.5. Its usually within 1/2-1 MPG's in its defense. Anyone out there running this tune as your DD? And what type of MPG you getting??

My truck doesn't like the 310, but the 345 is showing around 18-18.5

interesting , mine gets crap MPG's with 250-275 but 310 seems to do the trick. You use 345 as a DD?

I have been using the 345 as a DD lately. I don't use my truck everyday as I have a company truck to go to work, but I drive my truck every chance I get.

The KEM 345 in my truck showed 21.8mpg on the lie-o-meter on the highway at speeds of 75-80mph. I installed it yesterday and have about 130 miles on the tune I will hand calculate when I fill up.

345 tune 14.5(+/-)mpg 310 1 fill up so far 16.00mpg hand calculated. Im liking the 310 as daily d. Im easy on it so i dont get snappy shifts. 345 comp showed 21-21.6. 310- 22-22.3mpg. Hwy cruising the 310 has higher FRP and boost about 1/2-1psi more. But still better mpg.

have you noticed that the pedal itself feels a little tighter maybe even stiffer? or is this all in my head/ All the tunes 275 and under the pedal feels looser to me..can they adjust the resistance on the pedal?

The pedal itself wont be stiffer or looser.. Just the sensitivity changes. Didnt notice too much of a diff between 310vs 345.

i see......well the diff from 250 to 310 is a lot then because i notice it almost immediately.

You definitely don't have 3.73's getting that kind of mileage.

powerstrokin15 · Oct 24, 2011

yea, its driving wicked conservative. but like i said, pretty sure im running 3.55s

onebadf150 · Oct 25, 2011

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?

powerstrokin15 · Oct 25, 2011

I wish I could get this kind of mileage...

My last two tanks running the spartan 310 I have only seen about 12.5 with about a 50-50 mix...I am gonna run the 300 for a few tanks and see what it gets. then may go down to the 250 and see what it will do because the 275 would get me about 13-15.
