Ram is 2013 CC 5.7 6 speed. I have S&B CAI, 87 TB, Catch Can, & Bully Dog Tuner set to stock as I run 87 octane. Driving from Texas to Illinois, and all highway, maybe 300lbs in the bed with 4 adults in the cab running a/c the whole trip. My first tank I got 18.1 mpg (hand Calculated) driving the Texas, Oklahoma Speed limit of 75. On my second tank I got 19.5 mpg (hand calculated), this time I had cruise set at 71, Missouri, Illinois speed limit.
With the mods I have my city driving went from 15 to about 16.5 on average, thats a gain of about 2 which I think is good. According to the window sticker the estimated mpg is 15/19. if i can gain the 1.5 in the city why wouldn't I have gained at least 2 to 3 mpg on the highway? I'm not complaining about getting 19.5, but would have liked to have seen 20 to 21 or even more.
On the trip down I was towing a 6x12 Uhaul Trailer, we won't talk about that mpg...
Actually it wasn't bad, I got 13 most of the trip with exception of going thru the hills on the eastern side of Texas.
Back to my question, is there anything I can do to improve my highway mileage? Would swapping out muffler and Y pipe help? I'm open for any suggestions.
Thanks in Advance.
