What are the potential for this motor? Have power pup, cold air intake already. Would like to get better highway fuel economy. Any ideas?

 

I would maybe consider stacking the mp8 on top of that it stacks good with everything and it seemed to help my milage a little. Try keeping your rpms under 2000 that will help you out a little 1800 is what I try to keep mine at.

 

What do you consider 'better' hwy fuel economy? I just posted in another thread about getting a touch over 18 mpg, 18.4 actually, over the last weekend on a 465 mile trip. I set the cruise at about 75 and let her go. I can't complain, but if you have a way of getting better, I would be happy to try.

 

I am tired of the fuel mileage story. We might as well hang on tight. I want to see the Power numbers on these trucks. That's way more interesting.

 

I get 16mpg average with 18 on the freeway. (Legal speed) Thats what the computer says. Haven't confirmed it yet. It varies somedays with no reason.
07 quad cab
5 inch lift, 35 tires
6.7 with 6 speed auto
cold air intake, bullydog power pup

 

16th I am redynoing mine read my sig got a lot of mods for a 6.7 expect to over 500 hp and 1000 tq let you guys know when it hits the rollers again. Last dyno was 412 hp and 859 tq with 37" tires stock everything but edge juice hot.

 

Well Thats better then my 5.9

 

I don't know how you guys are getting mpg? I baby mine with 1200 miles and can only get 14.

 

Ive gotton 600 miles on 1 tank unloaded on highway. I get 8-9 mpg working with 20,000 pounds plus my trucks 8000 pounds

 

It will improve over time.

That's about all mine got new, but now with 10,000 miles I'm seeing much better numbers.

Hook up something heavy and drive it like you stole it.
