What do i need to change the seetings on my speedo?
I have a 97 ford f150, i went from 235's to 315's now my speedo is slower, but it fluxuates with increased speed, about 5 slower at 45 and about 9 slower at 70 mph, according to my GPS. What is needed to be changed to fix this? How much? Where to get? How hard to do it my self? And thanx for the replies.....
