We do get negative DA (10.99!)
Amazing what you can learn with a simple smart *** phone.
Anyway, air was -1250 this morning at 8:30...so it indeed does happen. The weather will hold thru Sunday and we race tonight and Sat night.
Air won't be that good, but should still be better than average summer air.
I'll give the C5 a whirl and see what happens. Hope the track is good. Skinnys will be on.

Trying t get rid of a little knock showing on scanner. I think he can pull off a ten if he can hook just a little better. Come on Ron

Stole my thunder Chris! 
Thanks to Rich. Damn smart *** phones!
Yes, 10.991 @ 123.72 with a 1.55 60ft. Pitt kept telling me to drop the air pressure. I was running 21psi and the car was dead hooking until the 4th run where it spun a bit and ran 11.03. So dropped them to 18.5psi and yahoo! I was the last car down the track.
DA was -800 on that run, at the airport, which is reasonably close to the track.
Very fun, you guys kept telling me the car had it in it....you were right.
BTW, I never touched the tune all night. I don't know why it had a bit of knock that first pass. Also showed really rich, but it came right in line with commanded AFR after that.
