Am getting Jmorgan's file installed tomorrow

 

Awesome. His best was .3 seconds faster than yours. The 170 lb difference would only account for maybe .170 seconds if you'll go by the .1 less in ET for every extra 100 lbs rule. He must have a more aggressive map than your current one. Having driven both his car feels a good bit faster. Yours felt similar to my car when it was GIAC Stage 2

 

Will be cool to see the Cabriolet deficit quantified. I have so many clients that love their cabs!
