On the 2nd and 3rd run, the clutch was slipping on the launch. I'm launching at about 3000 RPM and feathering the clutch as I come off the line, just like the other 7 times I've been to the track. My previous best was 13.292@103.93 on Stage 2 with a 1.888 60' &amp; 50 degF ambient temp(XR). My 1/4 mile times have not improved with the addition of the Autospeed DP, but my trap speed has. Guess I have to work on my launch some more.

You have the right idea. Get that launch down and you're at least 13.1X.

The R

Get the launch right and vary the shift points a little and you should be running 13.0...if not 12s.

On the last 2 runs I redlined first, but for 2nd and 3rd gear I was shifting at about 6200 and 6000 RPM respectively.

My launch issues this time was from a slipping clutch. I can get it to slip if I floor it in 3rd or 4th gear, so it's time to replace it. Since I will be going Stage 3, I'm going to go with a Spec clutch. I just need to decide if I want a stage 2 or 3. Seems like the folks who have Spec stage 2 are happy with theirs, as well as the people who have stage 3.
