I have 1997 5.2 4wd dakota. Best mileage I have been able to work up to (from 13.2) is 17.7 highway. I have done several minor modifications. Could I expect any better with either a new "chip" or different throttle body. ?

I don't know how it works fot a 97, but with my 2000/4.7, Anytime I can get more air into the engine, the computer resets and spikes the fuel to maintain the preprogrammed mix. I assume that when I install the turbos, the story will go unchanged.
Answering your question with relationship to my experience; The chip may allow a little better fuel economy, But most of them are programmed with performance in mind. So unless you can get one custom programmed, my guess is no better economy is avail this way.
Regarding the throttle body change; go smaller, save fuel, and pay the price of reduced horses.
I understand that you may be able to buy a little handheld programmer that plugs into your cereal interface port under your dash, this may be the ticket for you. I've seen "THE CAR GUYS" on Hotrod TV use one on a chev truck.
Anybody else see these? are they avail for us mopar guys????

Eliminate the crank driven fan and go with two electrics. Good for 2mpg city and highway.

You will need to remove the original electric fan and replace it with a dual fan. Look at summit for some ideas on universal mounted fans. You might have to call them to get the actual dimensions or get a catalog that will tell you to make sure that the fan will fit.
DO IT IN THE DIRT
