Jay Greene fuel mileage tune.

doug2013 · Apr 14, 2017

Late arpil i will be making a trip from alaska to florida. I contacted greene racing in order to do a fuel millage tune for the trip, trying to get the best millage i can for the 4k miles ahead.

Has anyone ever used them for a millage tune ?
If not i will be posting what my millage is like from the tune. Currently i get around 10.5-11 MPG 90% city driving since everything is so close on post and what not. But hopefully those numbers will jump up. I will keep you guys posted as best as i can during the trip from the likes and dislikes about the tune.

I have full bolt on also using a HF 91 tune and I get low 17's hand calculated running around town and to work each day. I am also curious how a mpg tune would do and even the canned mpg tune from DS.

I'm mostly around 16.5-19.5 highway with Jay's 91 but that's with summer and winter blends hand calculated.

10.5-11 mpg seems kinda low. I do a lot of short trips, daycare is less than a 1/4 mile away and the elementery school is barely a mile, I'm getting 13.3 with a lifted truck.

I see you have a 2009, how many miles since the last plug change?

changed the plugs 5k ago when i got the truck. im talking about really short distances around post from the dining facility to the barracks and back plus the cold temps still letting the engine warm up a bit. I am working with greene racing on the tune, just sent in the first data logs for improvement so hopefully on my trip i see upwards of 20 MPG.

When you guys say 91 tune is that straight 91 or no ethanol 91?

straight 87 for me trying to keep fuel costs down over the 5 thousand miles i will be driving.

So after the first set of data sent to jay he emailed me a revised tune with improved shifting (firmer) so far ive went from 10.5 to 15.5 Outside temp still a little cold about 28-45 F throughout the day. still running around post for my clearing and the improvements are already starting to show curious to see what i get on the highway. Also i forgot to mention i have the MDS turned off, I dont want to put any extra stress on the lifters.

What year is your truck? Are you satisfied with the way it's running now? Do you like the harder shifts?
