Its the weather. I went to the track and ran 14.0 no problem (remember im at 5500 feet so take a second off almost for altitude so its more like 13.0) and it was like 55' and cool and slightly misty almost outside. Perfect weather. I went back too weeks later. . . with more mods and could only do 14.5 and it was 98' outside. I ran my car twice and then poped the hood and bought a bag of ice and threw it on my upper intake and waited it out. Needless to say it never got cooler than 88 that evening. Cool, dense air makes a world of difference, in my opinion. But mostly becuase of my altitude.
