Whats your speedo out by? mine is out by like 6km/h when i am doing like 100km/h its reading 94km/h on the GPS anyway thought it might be just an issue with my gps but did a reset on my trip and went to work... it took me 25.5k to work... Wait a min... thats wrong i have been taking the same route for maybe a couple hundred times and i am sure its anywhere between 24.5 to 24.7.... is there anyway to recalibrate the speedo? how much would it cost me?
