Not sure what forum this belongs to but, I was wondering if there is any other way to calibrate the speedo w/o a programer. I have a 2wd 2004 edge 5spd. I have 285x70x17 KM2's. Also what mpg are you guys getting w/ a similar set up. I am also looking into 1" bl, and underdive pulley and whether or not to gear 4.56 or 4.88, so what are you guys getting w/ them set ups. I am getting about 17 (w/ my speedo off). I have a K&N filter in stock intake, and cat-back straight pipe.
