I guess that does simplify it, I just don't know if I would trust the canned tune that comes with it then when you are not in HO mode, just running regular pump gas premium unleaded with that hellraiser upper pulley. That's their problem though if they are offering this stuff with a warranty, maybe I'm worrying too much.
So Demon HO mode is 840 hp, with this pulley HO mode is about 890 hp? Stock/regular street tune is 802 hp with regular gas with 3.17 hellraiser pulley installed???
