Tax Return: To re Gear?

I am thinking about re gearing with my tax return. See mods in sig.

Currently:
I am currently getting 13mpgs in the winter here and 14/15 in the summer with 3.73 gears. Staying between 700-900 egt at 70-75, hitting 1000 uphill.

Stock:
I bought the truck bone stock I got 18/19 on the highway. (never drove in town before lifting).

Background:
My last 6oh had identical mods but I went with 4.56 gears and was getting 14 in town and 16/17 on the highway. I do not tow anything heavy or tow very often. My main concern is getting some mileage back. I have tried the looney tune from vivian and xtreme street from eric both getting me about the same mileage.

The question:
Should I re gear? if so what gear ratio? I was thinking 4.30s? Like I said I am looking for the best mileage I can get with my lifted truck.

Also another option I was thinking was adding Meth. I have a buddy that got great results when running Snows MPG MAX. I do not have head studs and would consider meth for highway driving only.

the last truck with 4.56s


Current truck in sig, Thanks for the help.

If you dont tow anything, and your running a daily drive tune, i would just go to a 4.30 set or even maybe 4.11's. I have 4.56's with 37's wishing i went with 4.30's. 4.56's are great for towing but not really great for highway.

I am pretty sure I don't want to do 4.56s again cause like you said and with my last truck I know the 4.56s on the highway is not ideal. I have thought about 4.11's as well just not sure if that would be a big enough change. I am between the two 4.11s or 4.30s if I re gear.

I knew that comment was coming, that's why I said "looking for the best mileage with with my lifted truck". I would love to see what I got when the truck was stock 18-19 hw, but I doubt that will happen again, So I am just looking to bring it back up some and get the best I can with the truck lifted the way it is. (Also you should look into custom tunes, world of difference over the on the shelf programmers.)

I didnt mean to bust your balls I mean why dont you get a smaller truck as a beater around town to save MPG. I havent seen any 6.0 yet get better that 21hw with any kind of a tunner. Not even stock size. I get that here in Fl but in CO, MI, TN I get 13-16mpg because of the hills and mountains. I still thank thats good because my girlfriends Mazda 3 gets over 30 hw in Fl but in the mountains it sucks worse than my truck.

I have 177,XXX+ miles on it with it and its still running strong why would I need to change it? The issues dont happen if your not constantly changing the tune on the fly. I leave it on one tune and stay there.

Its hand calculated too. Dont get me wrong if I put the peddle down its not that high and normally its not but when I drive home to Texas or Colorado I use the cruze controls and thats what I will get @ 65 mph going slow as hell in the slow lane....lol
