I use wunderground for historical reference for atmo conditions. I also use the resources at modular depot for corrections and DA calculations: http://www.modulardepot.com/?show=resources

wow, so my best run from 6/1 corrected would be a 13.97 @ 101.18mph.

the X is definitely capable of 13.8

DA stands for density altitude. It's a standard way of correcting for atmospheric conditions to "ideal", or sea level. The premise is that hotter or more humid air is less dense than colder, dryer air, affecting the performance of an engine. Barometric pressure also plays a role.

Check out the definition on wikipedia: http://en.wikipedia.org/wiki/Density_altitude
