Felpro 1008's

Don't take this the wrong way but :What exactly are you the official of ? Who said anything about 500hp+ and who was talking about tuning ? The OP thought he saw something he didn't remember seeing before so he asked a question , this prompted me to realize I had just put a set on and didn't remember them having or not having what he was asking about so everyone else gave helpful information -as we say in Canada thanks for coming out there eh !
