As a employee with cummins fuel system. Cummins controls the standards for EPA. As of now there is no other manufacture can keep up with cummins fuel system. they are developing an V-8 with better fuel mpg. The V-6 out works any Ford or chevy light truck diesel and better mpg.

My brother in-law had major problems with his ford, the flex hose kept blowing off and oil everywhere. That seemed to me was alot of backpress from a restricted exhaust. never again drive a ford here.

I just bought the 2007 Mega w/ Hemi and I am interested in what specific mods you made, products you bought, to improve the mpg of your truck.
Thanks for your reply!

I have not completed all the mods that I intend to do but I put 31/2 inch dual exhaust cat back flowmaster 50 series muffler, one pipe in and 2 out both come out behind the rear wheels at an angle with stainless tips
Volant CAI installed. I intend to use a throttle body spacer and programmer but waiting until I reach 12,000 miles on the vehicle before adding, just to see what it would be, My mechanic told me that the truck wont run to full performance until it reached the 12000 mile mark.

Thanks for your reply.
Did you in fact see an increase in gas mileage when you added the CAI and exhaust system? If so, did you see a differance in the city mpg, highway or both?

If you work for Cummins it seems you'd know it's not a V-6. It's an in line 6.
Do not buy the Mega Cab is you live in a climate where it gets very hot, such as down south. Florida, Texas, Socal, GA, etc.
The AC is very undersized. They used the same AC for the mega cab as was used in smaller cabs.
Dodge has admitted to a lot of complaints about this, but has yet to fix it.
I otherwise love the truck, but living in S. Fla it is just intolerable 4 or 5 months out of the year.

AMEN brother! If you live in a warm to hot climate - DO NOT PURCHASE A DODGE MEGA CAB! I cannot say this enough!!! You will be so pissed off if you do. Dodge knows that it's a problem but won't fix it. If you have 80 degree weather then your probably ok and can get by but if you live where I do and it's 95, 100, 105 and sometimes can get to 110 in July and August then your flat out SCREWED! Even when the dealer fixed the broken recirculating door to A/C housing, it still did not produce sufficient air volume to the front or back vents. Not to mention the warm air coming through the vents. I drove the truck for 30 minutes and it still was not cold when I got home from work. As I said, I don't live at the beach but I live where alot of people live and that's in hot climate in the summer! If I use the A/C in the morning, late evening or when it's in the 80's then it's ok - But people use their A/C when it really gets hot not when it's cool or cold! Please somebody come up with a fix for the Dodge Mega Cab A/C since the Dodge engineers can't!
