I am very interested in doing some performace mods to my car, but I would like to get a feel of what mods produce what power. I know other forums haev threads like this, and we should try to put something together, too. I tried searching, but I really didnt find anything that was that organized. If there is already a thread on this, then just delete it... if not, someone should make this a sticky.

Post up mods to your GS400 and what you out down in rwhp.
