Hello, I’m getting ready to replace my rear end, I’m wanting to put a performance pack rear end in the car with the 3.55 gears. My cars currently a base model automatic with 3.15 gears. I was wondering if I will need to get a tune for 3.55 to have the Speedo be accurate again. Or since the wheel speed sensor is on the hub of the gears will affect the speedometer at all? Also will it affect shift points at all with stock tuning or if it’ll just rev quicker. Thanks in advance.
