Surprised at the ease of use.
Unit is pretty straight forward and works well. Had to play with the tire size twice before getting speedometer to read correctly. Note my tires from Manufacture said 34.6" and my final input into unit was 34.00" and the speedo is all good. Just remember to reset your vehicle back to stock if taking it to the auto shop if they're gonna plug into the OBD because if you don't it'll erase your settings and your hyper unit will no longer be operable for your vehicle..
