Well GENIUS, why dont you stop being so DUMB and READ you GOOFY FOOL!!!! It says 400hp but I think that'd be pushing it, figure on not running more than about 17psi on it and making around 300-320hp (I'm conservative) for it to live a long and healthy life

. If it was me I'd set it at about 15psi and forget about it. Dont forget you'll need to do something about fueling at those levels: upgraded injectors and at least an safc.
