I am not familiar with engines in question, but digitalizing the engines brought more power and LESS fuel useage than the their mechanical counterparts. It is like fuel injection couple generations ago revolutionized gasoline engines. Old 454 produced about 200 hp and were gas guzzlers. New equivalents go above 400 hp using less fuel.
Than putting digital engine in different car brings lot of issues of reinstalling computers that are married to the engine.

actually in the cummins the digitization and the more hp made for less fuel economy in a gas engine there was way too much going out the tail pipe unburnt
any of the guys that are running 350+ hp don't care what brand are not getting 20 mpg but the old 12v can do it keep rmp 1850-1950 will be the best mpg
the p7100 pump and the old ve pump are by far the best for mpg in my opinion
I drove a 98 and then a 99 and the 98 with auto got about 2 mpg better
I have heard that the 24v with the banks turbo and air kit you can get a couple mpg better

I don't know much about engines but once my truck gets tired I was either going to do this swap or beef up my 5.4 but that would only give it worse mph correct? Where this swap will give great power and a little better mots correct me if I'm wrong I'm trying to make the best decision for when the time comes.

I compare Mercedes diesel engines in my cars.
The last 3l engine with mechanical injectors delivers 174 hp and 35 mpg.
The next 3.2 l cdi engine 201 HP and 40 mpg.
Than obviously green guys come to the table and next model with urea injection got less mpg.

so let me get this right mercedes has it right and cummins has it wrong is that what you are trying to say
ok a mercedes gets 30mpg and weighs 3000 lbs
ad cummins in one of these trucks you are about 6500-7000 and a 12v gets about 20mpg
I would like to put a hitch on a mercedes and pull 20k and see what its mileage is
now if my math is right looks to me the power to weight ratio the cummins has the mercedes beat
urea now you can blame the epa for that not cummins ford or any one else
