Q: While using this product do you leave it attached at all times or do you run it for a certain amount of time then take it off after everything is calibrated. Answer this question
A: Hi Chris, Thank you for asking. You only need to hook up the Hypertech Speedometer/Odometer Recalibration Programmer when you are first setting it up. After you set it up you don't need to have it plugged in.
