i am just telling you what the system says. everything is calculated based on the spur, pinion, and tire diameter you type in and the the signal from the sensor. i know how to type in numbers and i have digital calipers to measure diameter, so i post what it tells me, until someone with the Exact same truck does a run and posts a different speed, i do believe mine stands. i also am talking about straightline speed on road with a highly modified truck and a one of a kind custom tranny.
