I average about 20-21, mostly country and small town driving. I have seen as high as 24 on the highway making good time, I would maybe do better taking it easier on the highway.
RPM & MPH on highway please?

Time for a trip to Mike L so you can run the big tunes! lol.

I'm sure it could be better if I eased up on the go pedal around town.

So far, I've had real good luck on the(Approx) 110Hp tune I made, it gets about the same MPG as my old PPE 90 tune or up to 1Mpg better so far depending on driving...I really love this EFILive so far !!:rockin

....not to mention all the benefits PPE NEVER had, Like trans tuning and the AWESOME Turbo brake feature!!:D:D






:cool:
Which efi? I see multiple options, I want all those programming bells and whistles

Finding EFILive tunes in today's climate will be extremely difficult due to the EPA crackdown. Any canned tuner that is CARD certified will give you better mpg than stock.
