Lower your rear tire pressure to 22 psi and you'll be able to pull 1.9 60 fts. That will get you into the 13s.

Used the calculator below, now I'm not so bummed out :biggrin2:

http://www.modulardepot.com/density.php

Based on:
Temp: 81°
Humidity: 29%
Track Altitude: 168 feet
Pressure: 29.29 in.


Density Altitude = 2473 feet ET MPH
Uncorrected 14.03 @ 98.73
Corrected 13.63 @ 101.53

I'm glad the numbers got better because I know you've put in a lot of work to get there.
