Default Lost MPH In Better Air??

wondering if my car is actually running lean, i lost about half a mph tonight at the track compared to last week but the DA was only 1000 at the beginning of the night and dropped to 900. last week it was over 2000 and dropped to 1900 yet i trapped higher last week (best trap was 108.32, 108.08 107.99) tonight my best was 107.77, 107.74, 107.67, 107.54) its only half a mph but you think in "better" air it would gain or atleast stay the same not slow down. guess i should have don live tune it.

nothing has changed on the car in the last week besides an oil change.
