This weekend was the first real public T&T at Keystone Raceway park. I drove the Buick 98 miles to and from the track, only changes off the street were putting my slicks on. I didn't log any of these passes so I was just watching gauges. The first pass I could not get the on the 2 step and left around 3150-3200 rpm off the stage right brake that resulted in my PB 60ft 1.61
I messed up shifting after that launch and skipped 3rd gear and went right to 4th. Went
7.7@92
11.94@117
Next pass I found the 2 step switch had moved 1/4" fixed that now the 2 step works. Again on the stage right brake with 2 step active this time 3500rpm launch got a 1.66 60ft and the car jumped hard and I mess up shift and go right to 4th again!
Went
7.2@96
11.40@119
Now it's late almost 11pm and I'm in the staging lanes just going over the shifter motions after the trans brake release and got it worked out.
Last pass: on the 2 step 3500rpm launch 1.63 60ft
Finally shift to 3rd and run it out 5600rpm through traps
7.0@98
11.05@122

Thanks, I have a lot of small things that need improved and will help out too.
I just need to hit it harder on the launch the rest will be right in line.

Thanks for the advise. I'm using a B&M pro stick shifter, I had to remember to hold the lever during the shift.
