I changed tires from 255 to 245 on my 06 f150 and the speedo was out, I had the dealer reprogram and it was still out by 5 km/hr.
I am installing an Edge Evolution this week to optimize for towing, I'll be programming the tire size at the same time.
I thought I had read that the shift points are determined by speed, if this is true, then it would have been trying to shift to early as my speedo read 5 km more than actual speed.
