Somebody is selling some mods on Ebay and want to know if somebody knows anything about it. He is selling a EGR block off valve and a coolant line bypass which he states will gain 5-15HP EACH! Somehow, I don't believe it myself. I've contacted him and he stresses it does, but I would like to know if anyone have heard or tried this. Input Please!

:sun: :flash:
Was I really going that fast Mr. Officer?
