[Mjdtexan]

hi im a new member just bought a 05 explorer to discover its getting 15 mpg on the dash and by my math a friend and work told me that the computer can be programed for better millage any body heard of this? i had a 98 explorer that got 22 mpg before
this what happened to fuel economy ?

nope, never heard tell of that one before

I got 18.2 yesterday

I still need to put the new heads on. My new job keeps me busy. I am thinking of getting another Explorer so that I can work on this one in the evenings
