or a 1000 hp shitty old 400 sbc with hairdriers. :mrgreen: :mrgreen: :mrgreen: :mrgreen:


as for cyls cutting out, how come every single person i know with a hemi or chev that cuts cyls doesn't see any fuel mileage difference from the same truck they had before with same engine without cyl cutout? huh huh ....huh


Its just marketing crap is my best guess, the AFM only adds about 1mpg at best from what I've read. I know this i wont buy one with AFM I dont care for the technology at all. VVT is cool though

There is a guy on GMtrucks who has been working with AFM and leaning it way out and whatnot. Last time I saw the thread he was claiming 30mpg but cruising at 60 or 65mph. Again dont really know and dont really care, I just wanna go fast, and not break alla time
