my mph reading on the scan master is about half of what the speedo is reading. Whats causing this? Is this hurting my performance or driveability any?.
It seems to drive OK. I'm not sure of if its running as good as it should. I have an old Caspers UltraChip in it. It origanally had the 85 MPH gauge in it but I put an 145 cover on it, but I dont recall ever doing anything to any sensors at all.
