I just got my new left over 2005 crossfire and I love it. I live in Orlando Fl and would love to get a little more horsepower. I bought what I thought would help my car off ebay. The person sent me a resistor and said all I needed to do was push it in to the brown wires on my air sensor. From what everyone else is saying I am a little nervous doing this. Can anyone help me safely get more horsepower in Orlando.
