How reliable is Desktop Dyno?

mshred, Thanks, this worked perfect. I think the start of this post was a question of how accurate these are. I used all of my current information and ran through the dyno program. Took that information and ran through the dragstrip program with temperature, humidity and altitude for a track we had data for in our log book. The 60 foot and the 330 times were dead on the number by only a thousandth. This was on a 96 degree day with 68% humidity.
