Thanks!

Yup, that info is critical for best performance.

We showed up last year at an event at Bandimere in Colorado to run against trucks all over North America.

When the smoke cleared, we were ready for the 11,000' DA that was present (103deg F at ~5500' and humid) and they weren't.  Half the entries couldn't even spool their turbos, so we went home with the hardware.  Turbo selection and tuning must be changed based on DA for our application.

Needless to say, you're fighting with one hand behind your back if you don't have this info to tune with.
What to do when it's a long trip, and you want to get as close as possible but don't know what the local conditions will be?

Try this, it inputs altitude and weather conditions when you select the date and time: http://www.dragtimes.com/da-density-altitude-calculator.php

I just thanked them, and asked if they would be so kind as to add Wendover, El Mirage and Maxton to the drop-down list.

Until they update it.  You can always use http://www.wunderground.com/cgi-bin/findweather/getForecast?query=wendover%20ut&wuSelect=WEATHER 

Just have to have 2 windows open instead of one

What brand is it Sparky? What do you use for an EFI fuel pump?
