Did you filter WOT only?

Yeah that's WOT only. Only some low end timing changes and shift points. That 'post gear' run was the best MPH so far with the truck.

1100DA difference between runs is night and day IMO...
A perfect example is the day before yesterday it was about 65* out and my truck reallllly likes the cool temp. From a dead stop I can roast them no problem into second. Today I tried the same thing and it spins a little then gets traction, but it's 82* out and more humid than AIDS

Well, rule of thumb says .1 in the 1/4 for every 1000'. In my experiences air temp itself made more of a difference than overall calculated DA. Which would say that I think 15 degrees would be worth more than just a tenth.

I think you should run it in some cooler weather and see how it goes. I ran my best full bolton time the week before they closed the track for winter. I went back in late spring to mess around with some friends and ran 3/10 slower. About 35* difference in temp.
