Alright so i was driving down a road by my house where they police had set up one of those radar things that tells your speed. I wasent really watching at first but i noticed that my speedometer was reading 40 but theirs said 32. Ive tried this 3 to 4 times and have gotten the same results im considering taking it to a local shop just to have it tested on a dyno. Any one else experiencing similar problems? I mean i know because of the tires and stuff its not supposed to be perfect but an 8mph diffrence is just a little distrubing. Any one have any suggestions?
