a few questions on the 7.3

Hey, im new to diesels. Im choosing between a ford 7.3 and a dodge cummins..i have a hard time bringing myself to buying a dodge because i really like fords, but the gas milage that they get is amazing. my friend has a 2003 cummins 2500 with a chip and intake and exhaust and with his chip turned all the way up he gets around 27mpg on the highway.

if i am to get a 7.3 stock either 2wd or 4wd what milage should i expect?

if i am to get a 7.3 and modify it (i.e. chip, intake, turbo back exhaust [either stacks or just out the rear], new turbo impeller...and probably a torque converter and a valve body just to help the tranny out) anyone with close to these specs?

Your buddy is full of it... I do believe the cummins will get better milage then the PSD when build right, but the only way he is getting 27mpg is if he is up on a flatbed getting towed...

Stock 7.3 will get you about 13-18mpg... Moded with chip and stuff, 13-20 maybe...

what do you have done to your truck? i was planning on getting a good chip...either edge or flashpack or banks 6 shooter? any suggestions? i need somewhere around high teens low 20s will be great!

we had 3 dirtbikes in the bed of his truck going down the interstate5 freeway to san diego and the mpg meter was reading at 27 and high 26s...dont know how accurate those things are but he said it seemed accurate when he calcuated at the end of our trip.

Once a chip is added the overhead mileage indicators get confused and are no longer accurate. The only accurate way is the fill the tank to the top of the filler neck (Carefully) and then fill back to the same spot and calculate by hand.

When you start adding chips and injectors to those truck the mileage meter gets way off. The only way you can check it is by actually calculating it by hand.
