I heard that the 2006 HEMI's will have the MDS function for better gas mileage. Do you think there is anyway to install this on an older model HEMI such as a 2004? I'm not sure what would be required, if it would just be a different computer flashing or whether this would require a whole new engine or heads or something. Let me know what you think. As for gas mileage, I'm turning at best a 15 mpg for 6 days of driving. I have a 25 mile drive to work each morning, mostly highway. I hope to istall a K&N intake today and flowmaster catback within a few weeks. I also noticed my tired were 10 lbs under optimal pressure, hoping filling thos will eliminate some problems.

RE: Mileage mods
As much as I love my new truck, I heard reports this morning that gas could go as high as $4 a gallon. 
I love the Ram but at this rate I might be riding a Huffy to work. I figured the MDS options would be a little much to install but I figured I'd ask.

I have the 3.7L with a 5-speed manual and I am only getting about 13 mpg right now, but it is all city and I do mean city...as in you go a block and stop, go a block and stop...really sucks but it is the easiest way for me to get to work:-(. When I have enought cash set aside going to start needign help with mods to the truck though...so start thinking for me guys...looking for good bang for the buck, but I can't lift my truck:-(.
RE: Mileage mods
Well, I've been thinking about performance chips, wondering how much I could tweak the computer to get better gas mileage. Anybody have any idea how much you can get out of a chip as opposed to intake/exhausts?

I've gotten a solid 2 mpg increase with the K&N FIPK and Gibson exhaust alone. Since I put a tonneau cover on, i can see another mpg better on long highway trips. Of course the money I save on gas isn't gonna come close to paying for the mods, but the mpg wasn't the only reason I did the mods, I'm more concerned with making my truck last 150,000+ miles. By the way, I got my averages for mpg by driving 70 mph 50 miles a day on highway and about 10 miles city driving per day. Just thought I'd put my two cents in while I can afford it....who know with this gas increase....$2.25/gal for 87 here in NY. I better get my mountain bike out!!!!
