Howdy Guys ,new to the Forum(best one I've ever seen) have a love hate relation with my 06 3.7 Dakota,what I really dislike is that the Guys with the V-8s claim as good or better gas mileage then my truck gets,I would like to to help things a little bit(already have CAI installed{super turbo muffler didn't help a thing,it finally rusted off} what do you recommend? E fan? or underdrive pulleys?,looking for bang for the buck ,mpg improvement desirable too,I see a brand new E-fan from Dorman for about 160$ for a 2010 ram V-6,will that work-hello and thanx-Kevin

Use supper unleaded. You will get 1-2 more miles per gallon. No a good bang for your buck in millage but the added response you will have will be well worth the price. After a few tanks if you think there is no difference in power go back to the cheaper plain unleaded. Before the tank is empty your going to be hardly able to wait to filler up with premium. So you can have the power back at higher speeds. I just can't figure out why this is not on your list of modification for this six banger.

Well that's a pretty good list of things to start with. I swapped my gear set out and managed to find a set of 373's.I was gonna do the 410 deal but had some concerns about high rpm for hwy driving. What I would like to know is anyone here tried a supercharger or turbo setup yet? Just wondering how much more grunt could be gained from trying this out?

Sounds like a turbo set-up can be done but some internals need revamping. Lou.

I believe you'd be going the wrong way with the 3.21. That's 10 % lower than 3.55, if that's what's in your Ram. You'd need a lot more throttle to maintain your driving style and most likely never see the "eco on" light up unless you're going downhill or coasting. It's been said that gas mileage is maximized at rpm's where torgue is at it's max. If true, you'd have to drive faster, but then increased wind resistance would drag your mileage back down. It's a no-win situation. I do believe that factory engineers knew what was the best all around choice for your particular model and tranny. My favorite saying is always "if it ain't broke, don't fix it"
