My guess is cold air intake with less restrictive filiter and free flowing exhaust and a computer reprogramer and maybe a larger Mass fuel sensor

Throttle body, header, newer intake if pre99, exhaust,Injector upgrade,computer chip, aftermaket cat,cold air kit, less weight, cooler engine compartment temps, better radiator, throttle body spacer are a few things that can help performance.
