HEMI MDS questions

the problem with comparing the cars is that the pcm is different. The weight of the car is different ect. The ram pcm will not behave like the car pcm. There are too many diffrences. And you drop the hemi in a 3000 pound car (ie an a body) vs a 4000 pound car or 5000 pound truck and your going to get way better fuel milage. (assuming the driving style doesn't change) because the motor has so much less work to do to maintain speed. And a non mds hemi will probably see 25mpg at a cruising speed going donw the highway.
