I have a race coming up and the guy is in a Sentra SE-R auto with a cat-back. I have a ZX3 with a catback, pacesetter shorty header, and an AEM cai. I really want to ^#$& this guy up so if anyone knows of anything I can do quickly (besides NO2) please let me know. Also, how much estimated hp/tq does he have and how much do you think I have? I get up and go MUCH faster than the sunfire I had with the same mods + pulleys. Anyone have suggestions? thanks in advance.
