I just bought a 02 2 door gtp. Car has been sitting for a year and has 94k on it. It already has borla cat back and K and N intake system, and I just ordered a 3.4 pulley system, u bend delete, and jegs coils wit MSD wires. I am on a budget so can't spend much just wondering what other parts I can do with a decent amount of money and average installation that I can get the most power out of?
