Personally I didn't know it was your car, and I have been very pleased to hear about someone willing to tinker in the way you have... like the last issue. un kinking pipes and stuff... awesome, and I believe that 550hp is plenty enough and what you are doing to the car would even allow for more so it's easy to refute the power crud... on top of that you aren't mr.drag racer as so many people have come to identify with... true racing takes a lot more than 1500 ft...
Secondly, from a legal standpoint if you shoot someone trying to protect some type of posession is illegal, you have to be protecting your family or yourself... found this out recently..................................................................................................... in class!!
