That is right, NINE miles per gallon. Have you guys ever had mileage this low? hemifever wrote me a performance tune and that was the result after very conservative in-town driving in a basically empty truck without any towing.

He told me to set it back to stock for a tank and see how it does and I can already notice an improvement in shift time and exhaust smell. The way he had it set, the shifts seemed to "hang" forever before going into the next gear. Also, the fumes when sitting at the drive-thru at the bank, McDonald's, etc. almost made my eyes water.


I'll see what I get now that it is back to stock and then he will write me another tune for mileage from there. Wow,I didn't realize that this thing was an 18-wheeler.

 

thats what i used to get till i installed the hypertech max energy. now i get almost 12mpg.

 

Wow, Ididn't know anyone else got mileage that low. 12 is acceptable but I would think that these trucks would get even better mileage than that with a free flowing exhaust and various other things.

 

I get around 12-13 usually. If I drive it hard a little down to high 11's. If I drive it hard around town I can get down in the 10's. I may get 9's if I just hold it to the floor the whole tank of gas but usually it's int he 10's with me driving it pretty hard. I do have a Hypertech PP3 but that didn't seem to affect the mileage much as I still got similar before. It might have helped a tad bit but not a ton.

 

10 MPG here, empty or full. It doesn't seem to notice a load or a trailer, but it's ALWAYS dog slow.

 

You were also using the "performance tune" which is not designed for MPGs. After he writes you an economy tune, see what you get.

 

WOW! I get 17 MPGempty on the highway and 12 MPG highway towing a loaded car trailer in my 4X4 with a 5.2 and a 5-speed.

5.2 with a manual. That really seems to be the best combo for the Ram. KEEP THAT TRUCK Priest
