Woah!!! I just got back from a cruise in my GT. All I have to say is that unless you plan on drag racing this car, it has all the horsepower you will ever need! I am not going to waste any more money on horse power mods when this thing is already crazy fast. 3rd gear over 4500 rpm, wooooooooooooooah, is way illegal before you know it! More than enough power to finish yourself off rather quickly! LOL
