I am just wondering wat everyone is getting on the hemi. I have a 2012 ram 1500 sc/sb 2wd and have been averaging about 17 mpg. Thats driving pretty easy back and forth to work on a hilly, windy road. I have installed a K&N cai and a bully dog hemi plus tuner recently and havent had a chance to see wat the improvements are with those yet. I also have a flowmaster muffler. I would like to know wat some of u guys are getting on the hemi with the mods that have been done to the trucks. Thanks, J-Dub.

Mod list is in my signature, but I had been in the 16s during the warmer months, but have dropped to the mid-15s with the cooler weather. However, I haven't filled up since the Trinity was installed so hoping it will improve it. The EVIC seems to like it, but I usually get up to 1 MPG less than what it says. Looking forward to what the E-fan might do for her.

During the summer months I'm around 14.7-15.5...my driving habits do tend to change a bit, lol. But lately, I'm not sure if it's because of the drop in temp or from installing the sonnax line pressure booster because they both happened on the same tank of gas but my avg right nos is 14-14.5. But I do have a fair number of mods and I'm a lead foot driver at heart.

I should add that the numbers I gave were calculated by actual miles/gallons. My EVIC reads 16.8 while I would actually get 16.4 during the summer.

14.8 on 87 octane. 50/50 mixed highway and city driving in 0-15 degree Alaskan weather. The highway can be slow sometimes. This was my first tank from the dealership.

Currently running mid grade which I think is 88 octane. EVIC is showing 15 mpg since I reset it on the fill up but had some slow commutes due to weather.

I also run 4auto almost all the time FWIW. And I dont even have 500 miles on the engine yet.

I was averaging 16.5mpg before putting on smaller tires and the 93oct tune. Now I'm getting 15mpg. All hand calculated. It's really hard to drive this truck easy to be honest.

I drive a lot of short trips, so I'm sure it's not great plus the heavy ass wheels and mud tires don't help. So anyway I don't keep track, kinda scared to know lol

For the folks with less than stellar gas mileage, what psi are you running your tires at?
