speedo help!
well my dad thought his car came with 3.42's..the vin has GU2 so it would be a 2.73 rear end..no now my uncles car has 3.42's and his speedo is off..the only way my dad can figure out how to change it is with a hand held tuner..does anyone know of any inexpensive tuners? the HP's my mom found for $500 but i dont think my uncle will pay that much to have his speedo fixed, and were not looking to make power either..
thanks
