I just put in a PHP Phoenix 6 pos. chip in my 2002 Excursion with the 7.3L diesel. When filling out the online order form, I entered the stock tire size, and the current size with my 4" lifted set-up (35s). I was under the impression that my speedo would be calibrated as such by PHP. Will this chip fix the speedo error on my truck??? Thanks
