I was thinking, and this may sound dumb but the AFM on the L99 is controlled by oil pressure and load ratings into the ECM and blah blah blah but what if you could use a "line lock" system to keep it in 4cyl mode on the highway? I would think these cars could get 30-35mpg highway in 4cyl mode and that could help the CAFE and possibly keep from paying the dreadful gas guzzler tax..I mean really in 4cyl mode, it is a 3.1L 215hp motor I would assume that should be enough to keep the car going 75mph on the highway?
