how to get better gas milage
I'm on a mission for better milage out of my 06 FX4 (auto w/4.10s)
So far I've found that tire pressure (38F 40R), underdrive crank pully, and the x-cal 2 programmer have been the best. I saw no noticable improvements from a K&N (conical filter with tube kit) and a magnaflow dual outlet cat back.
One thing interesting IMO. I generally drive very easy. But I see no real difference in 50/50 driving when I accelerate moderately heavy as compaired.
My best so far has been 22.2mpg and did'nt have the tuner then either.
Just filled up this morning at 22.0.. but I've been playing with the tuner and shift settings. (heavier throttle than normal)

Well.. to be fair I started out in Nov. So the milage really can't be a direct comparison. But.. back then I was in the 16-17 range.
One thing that's hurting me if anything.. is that 23 is under construction so I'm doing more stop and go driving than normal right now. Gotta tow a 1000lb trailer this weekend too.. so it'll be a few weeks until I get a clear picture of what it's doing. I can tell it's better with the tuner though.

^^^They are, but I get 21-22 in the summer in mostly city driving, if I could get 24 and have better performance for all around and towing, its worth it to me. I still want to wait and see what Rich (wydopnthrtl) results are though....

18.5mpg @ $3.29 a gallon @ 20,000miles per yr = 1081gallons = $3556.76 per yr
20mpg @ $3.29 a gallon @ 20,000 per yr = 1000gallons = $3290 per yr
So for me and the way I drive I'll pay off the difference in 18 months.

I've got lots of mods and the only thing that made a noticebale MPG improvement was to keep my size 12 off the gas pedal. Either that or take the wifes SUV and use up her gas instead of mine...lol. Take it easy when accelearting and keep it at 65 on the interstate with the cruise control on. Those little buttons on the steering wheel are there, might as well use them. It's hard to drive slow and easy all the time, but it does help alot. I still can't understand how everyone is getting over 20mpg especially on your 4x4s. If I can get 20, I'm happy. If anyone watched the trucker myths episode on Mythbusters, driving 10ft behind a semi truck on the highway can cut your fuel consumption by almost 40% but I wouldn't try it.
Tonneau cover helped my gas mileage. I ended up buying a 1991 T-bird SC to use as a daily driver, since my round trip is 45 miles a day. I also did this to stop racking up the miles on the truck since it is not paid for yet and it has 85,000 miles on it. I have 3 more payments and it is paid off.
Update,
I filled up yesterday. Got 20.2mpg and drove 344miles. (no low fuel light) B-U-T.. this tank was very unusual driving for me. It was almost zero freeway driving. Mostly 50mph stop and go and I towed a 1000lb trailer for 70miles too.
I'm absolutely positive I'd never have seen this milage on the stock tune.
This next tank full which I'll refill on Fri-Sat will be a pretty accurate measurement. I fully expect to go over 400milies this time.
