I got one installed when I got my 4.10's in and the problem is it's 5-10mph off. I called the tech. guy and he gave me all kinds of different calibrations I entered and it still is 5-10mph off. I tested it with my gps. I'm kind of a worrier but if you guys think it will be ok i'll chill out about it I geuss. Is it hurting anything on my car by being off 5-10mph? I have been told to get a speedo gear but i'm not getting that plus my speedcal give me some input guys.
