Yea. GM will never couple DOD to a manual. The Cadillac 4-6-8 or whatever taught GM that people demand better fuel economy but won't even put up with a single jerk, pop, or shudder to obtain it.

People like cars that have 500 hp and get 80 mpg. It has to be totally seemless or we should go back to the 70's though.

 

run the car with no mufflers it will sound like a helicopter when dod is active otherwise im pretty sure dod only activates when throttle is <6%

 

I'm still clueless as to how people get over 15mpg in these things.....

 

Displacement on Demand is that the same thing they were calling Active Fuel
Management last year, is there any difference?

 

Same thing.

 

The GXP doesn't have DoD/AFM either on the 6 sp manual or the AUTO. Both GXP models have an LS3.

The GT has an L76 with DoD/AFM. The L76 is basically and LS2 bottom end with LS3 heads and intake on the top. It also has a small cam.
