Fuel Mileage

[yellowchevy]

The 2 main things that I seen and experienced in is your ready lift and 315 KM2.

Obviously the more lift you have the worse it's going to be. And I know it's not that much lift but one of my old pickup(1/2 gaser) was lifted 1 - 1 1/2 inches and it dropped in mileage.

The tallness of your tires isn't hurting you, it's b/c there fat. Which creates more rolling resistance and in-turn takes more energy to roll them.

The tall tires will only really hurt you if your pulling anything of good size and lugging the engine. As everybody knows the taller tires will decrease your RPM's which again makes your engine work less.

I agree with other posts on the EFI live. There are SO many more parameters that you can adjust with it.

i hand calculate fuel used based on pump fills and miles driven based on maps if i really wanna get accurate. i do usually use the dic and take 2 off of everything for just general conversation purposes. my post before is a general mix of both what the dic says and what i hand calculate from week to week.

my brother has an lb7 with fuel mods and programmer. gets 16 mog no matter what. sled pulls, pulling a trailer, hwy city drag racing it never changes. lol even plowing he gets right around that.

I have a buddy with a 06 and he gets 16 or 17. If my dic is off by two or even 3mpg i get about 20 mpg, and one time on a trip to Memphis from Little Rock and my dic said 27.5 so i had to be in the lower 20's doin 70mph.

When my foots not in it. 17 no more, no less. No matter what. Hand calculated off gallons pumped and GPS miles. But I have not calculated in a few months. Got a new FPR few weeks ago, wonder if that will make a dif? I'll let ya know after the road trip at Thanksgiving.
