Analyzing time slips and....

[TXsilverado]

found something interesting. im not too experienced in this so im hoping for some of yalls experienced input.

i went in april to hrp and ran a best of 14.882(75*)

i went yesterday to hrp and ran a best of 15.024(90*)

i expected my times to go up with the weather but what i found interesting is that my times were down but my mph was about the same or above. the changes made between the two runs is a nelson tune and i got a screened MAF.

heres the two best slips...

APRIL@75*
60'= 2.191
1/8= 9.56
1/8mph= 74.72
1/4= 14.882
1/4mph= 91.30

JUNE@90*
60'= 2.293
1/8= 9.724
1/8mph= 74.73
1/4= 15.024
1/4mph= 91.62

i had great traction on both runs. does this mean anything to anyone? i know my 60' is down but it seems like a low 60 would cut my mph all the way across...could a change in my tune possibly help?

I live in south La, so out weather is similar. I talked to an old timer today who drag races almost for a living, he said with this weather, you will run 2/10's high. Dont know about your MPH, I had that problem too last time I went, I was slower in time, but faster in speed, but I had new mods. I also had a bad wire though.
