What are you using for the accurate MPH read-out? The display could easily be adding 1 MPH to the precise reading to make the car seem faster.
The correct rotations per mile of the 215/45R17 Primacy tires is 844 according to Michelin. The differential has a 4.1 ratio and the gear ratios are: 3.626 2.188 1.541 1.213 1.0 and 0.767 so the accurate speeds at the 7450 RPM fuel cut-out are:
60*7450/4.1/844 ./[3.626 2.188 1.541 1.213 1 .767] which equals:
35.6 59.0 83.8 106.5 129.2 168.4
So you would need to shift to 3rd to reach 60 MPH. But, who really cares that the 0-60 time is slow because of the second shift?
