I'm changing from 3.55 gears in my 16 auto gt to 4.09 gears. I bracket race the car at the dragstrip. It has basic bolt ons and a dyno tune with the shift points around 7200rpm and rev limiter at 7800 rpm. I want to put off until the spring getting the dyno tune updated for the gearing change (shift points). I know the speedo isn't affected due to the placement of sensor on these newer mustang. I only have one race left and my question is:
where do you think the car is going to shift at rpm wise with the 4.09 gear before doing an updated dyno tune for the gear change? Before 7200 rpms or after 7200 rpms???????
