My friend has 2000 gt with an exhaust done. Well we are going to the track on test and tune night and i need to get something else done before we go so i can beat him. You can see in my sig what i have done so far. My question is from the factory what is the biggest drawback in our cars. Some say it is the intake and that the gt's come with good heads. What mod should i get to make sure i win? Are our heads and cam really good?
