I ordered a Diablo chip, with many emails and lots of help from ken at the store, but didnt have him program the chip to accomodate my 295/75/R16s. The truck came stock with the 2wd 265/75/r16 firestones. After having the tires installed i noticed what seems to be late shifts and the speedometer being off. I was just wondering if anyone had a similair situation and had their chip programmed for bigger tires? Thanks.
