advance your timing all the way and run 91-93 octane, you should notice a difference. Mahnaflow muffler also, i have a 4 inch cone works for me but i am getting a 9 inch just to make sure. I have gutted my cat and taken off my power steering belt. I run a 15.1 in quater mile, I can kick a slightly modded 5.0, and a gs-t elcipse. My friend has a 97 Grand prix and he has 7 inch cone and magnaflow mufflers and i can beat him too. Happy z-ing
