I need to do something about my dodges fuel mileage. I was thinking CAI and a superchips programmer but I'm not sure how much of a difference that will yield. I'd be happy with a 2-3 mpg increase.

Ok ill post a thread on the damage i didnt post it here just didnt think yall wanted to hear about it LOL.
As for the 6.4 Vs the 6.0
Big changes that were made were the 6.4 got Larger head bolts and can handle a lot more head pressure and are a lot more reliable. This truck also has not 1 but 2 EGR coolers ohh joy. One is right on the front of the engine and the secong is under the exhaust manifold drivers side. New style oil cooler that doesnt get clogged up like the 6.0.
We all mentioned the 6.0 problems.
Whats the 6.4 big disadvatages?
DPF system
EGR system
Coolant leaks
Bad Fuel milage in town
DPF system is the biggest pain in the arse peace of crap on these trucks, it sucks a ton of fuel when its in Regen mode, basically dumps a bunch of fuel into 7,8 clyinder to heat the cat up and help it burn <Clean> the Regen filter. During this you can get white smoke real bad, rotten egg smell, your can actually watch your MPG drop on the dash, plus it creats about 700 degree exhaust at the tip so its roasting the rear of the truck.
This also leads to fuel in your oil because it runs so rich during this process its not uncommon to see 2 qts of fuel mixed in the oil so they say you have to change the oil 3 to 5K and constantly check your oil level. Bad bad bad
Coolant leaks have been fixed on most 08 and 09 truck with an upgraded radiator so those arnt such an issue anymore. Also you was upgraded with a 2 oring upper rad hose, its said to be white one end and mine is all black so i might be doing that upgrade for peace of mind.
I choose to remove the DPF system, and when you do this you have to add a tuner of some kind to clear the codes and tell the truck not to regen. The truck wont even start if you unplug the DPF system. I then upgraded the Air intake as the 08 its not very good for anything over 400hp. Stock is 350.
So with my upgrades its as bullet proof as its going to get till i pull the EGR coolers later this year. these truck will handle up to 600RWHP or about 700 at the flywheel whith no real issue. Pass that or push more then 40 PSI of boost and your coing to be looking at new headgaskets and studs.
Duramax makes excellent power and its a solid truck, there only drawback when upgrading is the fuel pump. Do that and they make unreal power.Malo <--- Means--Evil or Mean One. This explains a lot.

Thanks for all the info mike. Looks like that's the way hes gonna go after I let him read your post. He was worried about the gas mileage on the 6.4 but seems like after you do a couple minor modifications they're not too bad.

After getting her all dialed in, using the proper HP tune, trans tune, going to work and back gained me 2.5 mpg I was getting 14.5 average and now im a solid 17.
Before in town only i was getting around 12 to 13 and yesterday i went 100 miles ruffly, into Portland to the Victory Motorcycle dealer and home and averaged 15.5 mpg so still a solid 2.5 average.
Can yall see what my next machine in the Mandley garage will be? LOL Victory Vision Tour is what im after.Malo <--- Means--Evil or Mean One. This explains a lot.
