i ask somone he told meme if i buy a MoTeCm600 and take off the emissions tune i can prolly make a extra 40 hp. in the long run.. if u wana do alot of mods.. u need the motec He told me ( the motecm600 is the best engine management system in the world as i know of. my friend uses his one to tune any motor in the world. u need the motec and u need someone that knows how to use it.. there are 2 add-ons for the motec which are needed for electronic throttle control. with this u can get 50hp more + borla cat-back 20hp + K&N air intake 20hp, thats 90 hp altogether which is more then what the factory supercharged aurion has )
