RPM id od and gas mileage
Hi all, i just bought my first ram and had a couple of questions. First is at 70 mph i am turning 2400 rpm's. Is that right? I have 3.92 gears, i checked. Also i don't think i'm going to be happy to find out how many mpg i am getting. I love the truck don't get me wrong, it's just that i guess i expected to see more mph with the v6. I realize it is a heavy truck with the quad cab. I have already upgraded the tires and rims with 33x12.50 17 dick cepek fun country II's. I also just ordered a leveling kit from performance lifts. Anyway i was just wondering mainly if my rpm's sound right to you guys at 70mph. Thanks, Aaron

Auto or manual tranny, and you already have the 33's on there? W/ the getrag 6 speed the overdrive ratio is 0.79 and couple that w/ 3.92's and factory 30.5 tires and you'd be turning 2400 rpm. Once you put the 33's on the rpm will drop about 200 at 70 mph.
