So does anyone know if the N54 pistons are forged ? I read a rumor stating that they were forged, which would explain the insane power levels supported by the N54. I see that they are made by Mahle. I sent Mahle an email and they said they can't tell for sure unless I send them the "code" found on such a piston. So does anyone have this important piece of information ?
