Most likely this is because you're hitting the limiter, so your shifting might be tight in all actuality. Where to short shift 4th might be a little bit of trial and error.

It also helps to write notes on your time slips for stuff like this. Writing launch rpms, where you are shifting into 4th etc, can help you isolate the effects of different things you try.
Thanks! I went back again last night, but even though I stayed to the end I got only four passes. :(

MY shifting rhythm and 60 foot were both off from my last time. However my ETs stayed about the same (13.3-13-8) and the shift into 4th cost me 2 MPH @ 108. The air was better and the temps were in the 70s. I also ditched my spare tire and the crap in my trunk. All in all I was disappointed in me. MY only improvement was in my RTs which were .5 or less. Still room to improve there. 3rd yellow. 3rd yellow. 3rd yellow.

I plan to go to the T&T Friday night and work on my launch. I was thinking I would try the Launch Control to become more consistent. Then once I have the rest worked out come back and work on a clean manual launch. However after reading more about it I think not.
