OK don't shoot me. Remember my Sy is the only truck I've ever driven/raced. It seems to me to run really well. But, like I said, I dunno. So hear goes. Here's the time slip then a link to the corresponding DM log. (Forget the dial that was for something else.)

Feel free to chime in with comments, criticisms, whatever...

Thats nearly identical to the best pass i ever made in my Ty on stock motor, stock injectors. ET, MPH and 60' are all almost the same.

Looks like at about 70mph, you start getting enough airflow to start cooling the air charge down. Right before that you are getting knock and losing a few degrees of timing.

Were you launching at 2-4psi? Brake limited?

Nice run. I am jealous of all you guys with running trucks...
