Id say it would be about the same maybe a little better seeing how a 5.3 is smaller motor..it also depends on what size tire and wheel you run and how much you are lifted if any..i have 33x12.50s on stock 17s....now if i cruise at 60-65 mph running around 1800-1900 rpm it gets around 15-16 mpg..when it crosses over 2000 rpm the mpg drops like a prom dress to 12-13 mpg

Well last night at the track I got out my tuner (Diablosport predator) to go through everything before I ran. For some reason my pe tables were maxed out, I did some tweaking and set it at 5% wot 2-4k and 8% 4-7k. After that I ran a 16.1, but I really have no idea what things need to be set at as I have never ran any logs or anything. A dynotune is in the near future so I don't have to mess with all this. Even still i ended up running a 16.1 on 34's with headers and intake and lifted with 3:73 gears which I don't think is too bad

Weather was just the same, maybe a little warmer. 2.57 60', 6.99 330', 10.55 1/8 at 69.24, 13.60 1000', and 16.162 1/4 at 87.63. How much do you think the wide band dyno tune will change my time? And I think there may be a slight exhaust leak but I can't tell because the headers kind of tick on their own. It only happens when the motor is straining like going up a long hill without downshifting. On my drivers side I have a header bolt that is broken off, it is the furthest back one, but you can't hear a leak at idle and it looks to seal up fine. I would have fixed this but it is near impossible to access.

How much would they cost to swap on a 4wd? Could I do it myself? And what is the mileage loss? Right now I go about 320 on a tank 😂

When I had 35s I went from 3.73s to 4.56s and mileage stayed about the same overall. City went up some, highway went down some, but it averaged out to about the same. Back then it was ~$1100 for everything to have them installed front and back.
It was a night and day difference in how the truck drove too. With the 3.73s it always felt like I was towing something, and 4.56s felt a little better than normal size tires even with the big ones.
