What range of DA readings does Vegas see?
3300 Ft in the winter and 7700+ in the summers at night
Ugh...
Some of my local Mid-Atlantic tracks are comparable to Woodburn, so I'm sure there can be a pretty big loss of performance going between those two tracks.
My pump gas Duster with no changes from Woodburn to Las Vegas lost two to three tenths ET and 2 to 3 MPH in the spring, my old race Duster would change .4 ET and between 3 and 4 MPH from winter to summer up there with no tuning
BTW, in late July and August it gets worst when the thunder storms are brewing
