yar yar. i confused myself a bit in my post. He said he would need "ID1600" for 400hp, which would be "maxing them out" (in his mind 400cc per injector). We were all wtf, because 1600 more than enough for 400hp. Turns out he meant ID400. Got that stubborn mind where when someone states xxxCC injector, thats the overall CC for the whole engine. Lol
