With the Stage 3 software in place, I decided to hit the track again to compare how my car did with my Stage 2 run last month . . .

Compared to the Stage 2 software, I definitely noticed improvements. I consistently hit 110+MPH which was something I was having trouble doing before. The results from my 1st run last month and my most recent run are below. Overall, my times are still weaker than other people that have hit the track with Stage 2/3 which I'm thinking is primarily related to my troubles getting off the line when the light turns green What'd you guys think?
