I have my new 2003 Cobra basically broke in. At least enough to where I am going to start haveing fun with it. I have always made power on the motor and never with an adder like this. I am getting a Predator, 2.8 pully, and a cat back. Later I will have and off road X pipe. When tunning with the Predator I understand about fuel ratio's and timing, so what kind of boost levels will I see? I also have a Pyrometer that I think I will install since I just took it out of my diesel and its just laying there. What are some temps(in the cylinders) I should stay away from. And since I only have one probe whitch cylinder should I monitor. Do these 4.6 motors have a cylinder that runns leaner than the others or does haveing boost get rid of this problem?
