Cummins swap, yes or no?

So I have a early 99 PSD F250. It has a 16" lift and 40's soon to be 44's. I was thinking a cummins swap for fuel economy and power since it is my daily driver and I tow a fair amount. I dont mean to start a war or anything (I know some people are attached to their powerstrokes). Or should I keep the 7.3 and do some mods to it? Anything I do, I want fuel economy to come first and then power (I have propane and water/meth injection, and a TS 6 position). I like mods that are progressive, ie I can drive around in town with a light foot and get good mpg's but when I get in it deep, it has what I want. What do you guys think?

what kind of MPG you getting now?

the swap will be very expensive.... it will take a long *** time to recoup the amount of money you put into doing the swap in the savings in MPG

your prob would never recoup it

Getting 11-12 now in town but I know I have fuel issues. Be it a bad pump or injectors or something. I am working on a full four link air ride setup and when I am done with it I will dedicate all my time to a swap or mods or whatever.

Since the pic, I have added 6 chrome reseviored shocks, painted cutout flares, a rollpan, and shaved the tailgate. PS dont ever buy Truxus tires, they are the worst

Your worried about fuel economy, but you have 44 inch tires.

if you're considering an engine swap and installing a cummins motor you should have bought a dodge. i agree with willholl79, your worried about mpgs but, your running 40 inch tires soon to be 44's.. doesn't make much sense.

Agreed. I would use the money to buy an old "beater" 4 cyl. car or ranger or something to drive around. Then use the fuel savings money to make the truck even more badass

I didnt say that I had to get every last mpg. I am simply trying to make it as effecient as possible. I understand that the larger tires are going to cut into my mileage and that is a tradeoff that I am ok with. I am simply trying to make it as good as possiblel.
