The opposite direction
I am posting probably the complete opposite of most "engine" mod questions.
Most people seem to want a loud exhaust.
I love my music and I installed a quality system in the truck to hear the music, not blast it over the noise.
I have a 4.7, I am interested in more MPG, less exhaust backpressure to coincide with the MPG's, and as quiet in the cab as can be attained. The stock exhaust is not to bad on my 2009, but I think I can gain 1 or more MPGs with a less restrictive exhaust.
Forget about the CAI, I believe the stock one with my drop in K&N is just as good, and a lot less noisy.
As far as chips/programmers go, I see most are for performance gains, not MPGs.
If there is one for the 4.7 for mileage, and better upshifting and some more hp when I need it, please let me know.
I do drive without a heavy foot, but am glad for the HP when I need it or when towing.
Right now I get an overall of 16 to 18 city and up as much as 22+ on the highway, cruise on, fairly level roads, my tool and parts load is about 1200 lbs +or-
Thanks for suggestions.
