It is a mustang dyno. There was actually one run in between the three posted on that graph. All the runs were roughly 10 minutes apart, same temps for all runs both outside, ECT, and IAT. It was a really good set of testing conditions as far as everything being equal and fair across the board.
I spent a whole day with a 392 charger earlier this week so I had a really good "email tune" setup and all I had to do from Rob's car is copy values over.
