Being na it was the best mod I did on my car.
It's run 10.82@130 for 2016 and 10.83@131 best for 2017 in decent air Dale. I want the car to run 10's in any air for 2018. Most guys I have seen running NA or a centri setup are running 4C's. If I have to pull it and send it back for a revisit then that will be done. You know from experience that Circle D is good about working with their customers. I'm going with what the PD experts say is working best with my type of setup.
