Since I am thinking about the teraflex 2.5 in lift and 35's I am just doing some research. What are you getting with a 2.5 inch lift and 35's. Please state what you got stock vs after mods. Please post what tires and gears. I am really interested in the 4.10 gears with a superchip programmer. I get about 18 avg according to the dash bone stock. BTW I have an unlimited. Just wondering what kind of a hit I can expect.

as for stock MPG I dont know...never been stock
but with 33's I was at 14 MPG and now with the 35's I am at 16 MPG

 

is that with a calibrated speedo in both cases

 

Lost about 1.5 mpg (17 to 15.5) on my Unlimited automatic Rubi from stock to 2.5" TFBB with Firestone 315/70 R17 (34.5" X 12.5") this is after correction for computer reading (you get 6% difference on the reading of the odometer).

 

I have heard repeatedly that the dash computer is incorrect when it concerns the mileage. It is almost says you are doing better then you are.

 

i just put 4" lift and 35" km2 auto 4.10 gears
stock about 14 mpg
with 35" 10 mpg

 

how hard do you drive your jeep to get 14 stock? I am getting about 19 and dont drive like I stole it but I definitly dont baby it?

 

I get 17-19 normaly. 15 while towing. 4 inch lift 37s. superchips flashpaqs

 

You can expect to lose 2-3 mpg.

 

YES calibrate at the stealership for 80 bucks
