Hey guys, wondering if i could get some assistance with recal'ing my speedo. I've got nitto 295/70r18 on my 2004 f150 lariat. what value should I enter into the evo and do I have to do a full reprogram (back to stock then custom level set)?

Thanks!
David

Your tire setting is 2734, according to the calculations on the edge site. You don't have to go back to stock. but you will have to choose which level you want, and then choose custom tune, then add the tire size. Try adjusting your shift firmness (if you haven't already). I run mine on level 2 with my shift firmness on 5, and it feels like a totally different truck.
