Comments - "the ability to crank your car up to 800hp for dyno duty then detune for 500 for daily driving is golden." - I find that I really need 500hp when I drive through my neighborhood at 30mph to get to the grocery store. *sarcasm off* No one has any legitimate need for 500hp in a daily driven car. Not trying to be an ass, just pointing out an error in reality.
Grammar police - you won't need "less parts", you'll need "fewer parts". :)
