BEST CHIP FOR LIFTED PSD'S!?!?!?!?!?!

[Deuces Wild]

Thinking about getting a DP-Tuner, Ive got a 2003 7.3 with 8" lift and 37's Getting 10 MPG (Stock) in the Puppy heavy footed too, Just trying to see what I can be looking at as an improvement in MPG's or maybe there is somthing better out there for what I have

5" Exhasut
Drop In K&N

Im in FL, and wont really Tow much much would still like the option. Heres what Ive picked.

# Position 0 No Start
# Position 1 Stock
# Position 2 80hp Econo - Daily driving for mileage
# Position 3 80hp Tow - recommended for towing 5K to 9K at sea level and
# Position 4 140hp Extreme

Now I know getting the Extreme wont help the MPG's, Im getting that for fun.

nice rig, I have the same color scheme on my 02', also have a dp and I like it so far and the 80e gets pretty good milage and still runs good, I also have the 140 agressive for playing around with, I could probably get better milage but the new hasnt worn off yet, only had for 2 weeks

The "extreme" tunes usually net better MPG's if you can keep your foot out of them.

What gears are you running?

EDIT: The K&N might not be the best choice, they have dusted many of powerstrokes.

look into this- DIY Intake

Im not too sure on the gears, I got the truck pretty decked out , The guy before me had some Money to throw around and I still havent figured out everything hes done to it. What kind of MPG's are you guys getting with the 80hp or the Extreme

Stay away from K&N! Great for gas, too drity for Diesel.

Is your front bumper mounted farther out? Is that for clearance or the light bar?

If you want some really good MPG talk to Matt @ Gearhead Automotive. Out of the different chips I have ran I got the best fuel millage with his tuning. But tuning isnt everything 90% of it is the driver. and you will still only see 1 or so mpg increase with a chip i don't care whos it is.

[stroken04]

What are your RPM's when your cruising at 70?

[layson]

I bet he has got 4.56 gears in that puppy... that will kill the mileage...

then the obvious questions are... are you reading the lie-o-meter or checking it by hand? Also is your odometer/speedo correct... that will throw your mileage WAY OFF...

here's a kicker with my 00 7.3 on 37s with 3.73s I get roughly 17 mpg highway...kind of afraid to up to 4.56s when I do my 40's....but I was wondering the same thing, I just bought a bullydog as a starter chip...
