To say that injectors (any brand/capacity/nozzle) will increase MPG is rarely the case. With any diesel engine, it takes a specific amount of fuel to make a specific amount of power. If it takes 60 HP to get the truck to maintain 55 MPH on level ground, then the amount of fuel will be nearly the same regardless of what injector is in the truck. Yes, tuning does play a bit of a role in MPG, but don't be surprised if you get similar mileage out of the hybrids that you do out of your current ADs.
An extra 100-120 HP worth of fuel is about the limit for the stock turbo (longevity wise, anyway) so the power output I personally would recommend out the the 238s would be no more than what your ADs are now capable of.
