Theres lots of mods out there, why not choose a better mod before you chip it, for instance have you done a exhaust, air filter, cams or vtec controller yet? U'd be best getting a stage 1 cam before u "chip" it anyway.
for instance, a gud quality exhaust, de-cat and filter can give u reasonable extra power i got a 15bhp increase in power and 10 f/lb in torque! plus u'll need to do these anyway before you do other mods to make the other mods worth-while!

Dont forget to upgrade your brakes!! if you wana go fast, u gotta b able 2 stop fast!! otherwise.......
