I've been told time and time again about the # differences between the dynos and I still don't get it. To me, whatever you actually put down at the wheels should be one number only, not different #'s from different dynos with all this percentage bullcrap. Just let us know what the car is really putting down when you mash that pedal to the floor. I'm going to get a baseline dyno on a dynojet on May 24th in Kissimmee, FL. It's good to know what the car is putting down before I start the modding addiction.
