BiGMaC, I am sure Dan is correct. My car is brutal in 1st and 2nd but sort of lays down as the RPMs build in 3rd. I left the car in Drive, of course, and I was at the end of the quarter before it shifted to 4th.
I wonder if I had shifted to 4th manually a bit sooner, if I would have had a better time and higher speed at the end. I am not sure how an MKS stacks up aerodynamically with a SHO, either. It just seems that 90-105 is my weak spot.
