gettin that good fuel mileage along with some other newb questions

[narsenault05]

Have the 7.3's been known to get good fuel mileage with addition of say a aftermarket turboback, intake and tuner along with some conservative driving? What are you all getting with similar mild mods? Gunna try to find an 01-02 when im back home from active duty. And i dnt have much plans for the truck other then turboback, intake, tuner...and level it or maybe a small lift to clear 35's...could i expect decent mpg's with some conservative driving? Also any major things to look for in the used late model 7.3 market? Any info is appreciated!

I got anywhere from 16-21 with my 7.3 depending on driving style. Similar setup to your plan

look for the 99.5 up so you dont have to deal with the e99 crap like me. Not a big deal tho cuz i love my truck! and at some point, i think 02 they switched to powdered rods. I think most guys would say the 2001 is the best truck? maybe someone else will chime in. When your looking at a truck do the blowby test by putting the oil cap on the filler upside down, the cap should just sit there. If there is enough pressurized smoke to blow the cap off the truck probably has some issues. Also if the turbo has that metallic heat treated color it may have been abused. Best bet is to look for a bone stock truck from an old guy.

lucky! i get 12-16 MPG wiht those same mods.. and a 2" lift on a 99 (i know certian years came lifted higher from the factory) can clear 35's. i have a 4" on the back and a leveling kit on the front of my 99 and i cleared 35's with no trimming, and 37's with a little cutting with only the front bumper

Best I have ever gotten was almost 17mpg, doing 68/69 on cruise on the freeway. Around town usually somewhere around 15. Towing has been known to drop the mpg into the single digits

I have 4" turbo back exhaust, an intake, and Superchips Tuning, all highway at 65mph, I can see 22.6... My average overall is 17.8. I think the lowest I have seen hauling heavy was 14.2 on a tank. I am 2wd though...

All hand calculated.

I have an S&B cold air intake, 4" turbo back and a Bully dog chip. In the +75 hp setting I see about 15-16 mpg stop and go.

I usually get around 15-17mpg... All I have is a DIY Intake and straight Pipe...
