Speedometer not correct, months after being correct
So at start of summer I put 3:73 gears into my wife's car and changed the tune to 3:73 gears. It worked perfectly for months. Recently had her tell me speedometer is off and car is shifting weird. I just pulled the tune in the car and nothing has changed??? Basically if your doing 65 mph speedo says 75ish. Should I try just reloading tune?
