I think you have input the tire size incorrectly. You should be inputting the actual tire size ( 29" x thickness). I've never seen a computer that actually asks you to measure the circumference of the tire.
Faster speed and longer distance would be a symptom of the computer thinking you have a larger tire size than you do.
