I know they are hard to tune but what exactly do you have to change, I kind of want to put them on my car but I am wondering if you can still have it streetable, and two what you have to change in the tunning to make it work. I have a guess that both the fuel map and something in cam timming but i'm not sure. Anyone willing to give a breif explination that would be great. I plan on making my own and am trying to read up on tunning them. Thanks
