Yes. BUT ...
Is there a negative DA where you stop picking up ET and MPH? I've discussed this with some Stock Eliminator racers as I'm very careful about tracking DA when we run on my phone and a weather station. We ran in Dallas in the fall and the DA was well below sea level. However, when you get down so far isn't that all the better the air is going to get and anything lower won't help?
Just something to think about ...

I don't think there would be too low of a DA....basically a free blower (all that dense air acting like one) But IF you don't tune for it...yes, no gains once you get to a certain point.
on my previous platform I ran in many different da's ( usually well into the negatives or I wouldn't be there lol ) and I can say -1500 will run a solid 1/10 better than -1,000 and from watching some of the times that come out of Atco in Jersey that stays open into December -2000 and better gives even better numbers.
As long as your fueling is increased to match the extra intake charge you should make more power. The only other issue with lower/better da is if your car is fighting traction to begin with its only going to get worse as the air and track get colder , you need to take advantage of the great racing weather.
Another unrelated issue can be the people that don't know the difference between the street and the track that think they can stay in it even if they aren't hooking and drive out of it , at some point most tracks will hook and you will go whichever way your pointed when you hook - see way more knuckleheads in the guardrail or the other lane around here when the track gets cold (coupled with making more power).
