Compute the Density Altitude each time you run... Correction tables aren't 100% accurate all the time due to other outside factors, but they can give you a general idea of how fast you should be able to run in comparison to the lower density altitude when weather is good.

Sometime this fall/winter I want to take a cruise to somewhere that's sea level and cool - I ran 11.93 in Las Vegas where the DA is routinely above 5000', the correction factor put me down to 11.19 at sea level.

I didn't believe it before...but now I do after reading some peoples' posts.

When my truck was BONE Stock it ran 14.79 in 40 degree weather and slowed to 15.20's or teens in 80 degree weather.

I haven't ran it with the blower set-up, but I'm down 3 psi from my normal 12 psi. I know it is probably some belt slippage, but also the friggin 90 degree weather and 90 percent humidity has something to do with it too. I know it felt a HELL of alot faster back in January with cool air and 13 psi . Can't wait until October to roll around to get some times. I don't want to go to the track now for fear of disappointment.
