Just seems like a ton of technology and what-not for very little gain in mpg...on top of what is perceived as driving a "performance" car on four cylinders...dunno...
I know back in the day, manual trans cars would get better mileage with the same motor. So maybe an Automatic LS3 would get 2-3 mpg less then a manual LS3 so the increase of 1 mpg over the ls3 manual may be 3-4mpg ls3 auto vs l99 auto... Make sense?

Now I understood the LT1 dod/afm on/off was turning on/off the ability for it to go into 4 cylinder mode.

example:
dod off (always V8)
dod on (just like L99 cars, the ability to go into 4 cylinder mode)
