latly i have noticed a drop in millage. i have been only getting 300 milles a tank. i usally put in 24 gallons. now i do have bigger tires and thats why the millage is low but i used to get close to 400 milles a tank. i can't belive the tires screwed up my milage that bad. the truck runs great. i am just hoping it is not a injector problem.





Do you all have any info that might help?

Have you been compensating for the larger tires and doing your MPG math, etc. using the error factor? I run 315 70R17's so my error factor compared to stock is 11.33% (slow) which means my speedo and odometer are all off this amount and I must take this into account when figuring mileage, etc.

yes i am figuring the tire size change. i am 8% with mine so really i am getting 324 miles which is still crap.

What mileage are you calling crap? I run a 4" lift with 35's and I'm getting around 16-17 mpg

i am getting 12-14MPG with a light foot. witrh the juice 4 in straight pipe and air filter and my millage isn't good at all.

U are running the juice in level 4?


Try taking it of so it is stock and see what happens.

yes i do run the juice on level 4.





but it will be hard to go with out the power. lol

Drugs and Juice are additive.......level 4 daily driver.....whew!


Had to edit this, can you say "light pedal", "Juice level 4" and "I can't do without the power" along with "poor mileage" all in the same post?????
