Ok, I don't know if this has ever been covered or not, much less do I know how to search for it. I heard from a guy who works at a Toyota dealership near my work that if you open the top of the mass air flow sensor, and turn some dial counterclockwise 3 or 4 clicks, then seal it back up, that it'll add some 30hp. Anyone ever heard of this being done? Thanks!
