The DA will change by the hour, but phisically you should be at a fairly low altitude in Washington and can make a big difference in ET and MPH if you can get into the negative DA.
I had your exact same mods but had a 3500 stall, went from 13.4 @ 104 to 12.7 @ 107 on a good day. But different tracks seem to vary around the country and I run at a slow track.
