That's because you have 3.73's. I was told to use 4.10's because I have an automatic. Definitely had to have the shift pressure/point from 1st to 2nd adjusted after install. Was chirping and setting off the traction control everytime it shifted from 1st to 2nd. Now after the tune you barely feel it shift between gears. Feels great. I'm not a racer, just trying to get the most umph out of the car. How does your car shift between gears? Is it an automatic?
