If your spinning your losing time a couple of ways. Even with traction control off, even with a wavetrac, the transmission will shift early at around 5000 rpm in first which puts you in a lower rpm range in 2nd. So you loose the power at the top of first and have to go through second from lower rpms. If it helps you, I was running 13.3 at 107 so the mph makes sense with the ET. The altitude and lack of traction are your biggest obstacles.
