Really,.....What's the Deal?

04.5 2500HD D-Max CC 4WD Bone Stock Running 285/75/R16

I had my mind made up that I was fixing to go on-line and order: AEM intake, MBRP 4" Exhaust(Cat-Back), and most likely the PPE Economy Programmer. I decided I was gonna spend that amount and try and squeeze a lil' more mpg out of my truck(adding to that..next tire set will drop back to stock size). Well, I find this older thread on here discussing exhausts and benefits of lower EGTs, but info was stated in that thread of how it(larger exhaust) doesn't really benefit economical aspects of truck. I want to spend money for economical benefits..not sound !!

So......:cool......order all three or just some of the above and save the extra $$ for that new set of tires?

Ordering all these parts to get better MPG and save money of fuel is crazy. If they save you $10 on fuel every tank it will take you 110 tanks of fuel to pay for the parts before you ever see a return on your money. 110 tanks of fuel is about 65,000 miles of driving. Buy the parts for the horsepower like the rest of us and then talk your self into the fact that they might get you better MPG. Once you have these things on your truck you will drive it harder because it is fun and MPG will do nothing but go down.

Forget the intake, Get you a good filter. Get the exhaust and programmer. IMO I would do a cat and muffler delete. And go back to stock tires. All will help improve your mileage.

Don't need to. My truck will pull my trailers and my fifth wheel just fine. My truck getting accessories is not an ego trip for me..............

Care to recommend a great OEM drop in replacement filter that IS NOT an oiled filter?

Just an AC delco will work as well as any. It's not and ego trip. I choose to buy parts for my truck instead of smokin crack and going to the bar.

There are many to choose from. But the delco, will work just as good. The only need for an intake like a CIA. would be if you want to run some BIG horse power.

You can keep the stock exhaust and just do a cat and muffler delete to help with the lower EGT's and to let it breath better. since you stated that you pull a 5fer if you do go with a PPE programmer I would get an EGT/boost gauge setup just to be safe.

Well I'll tell you that for me, after adding exhaust, my mileage went DOWN. After the programmer, it went back to normal again. Then add a CAI and it was pointless and a waste of money. And one thing you have to remember is, running a tune and towing at the same time is not good for the tranny....some people do it and have no problems, but there is no guarantee. So if you are buying all this for a mileage increase, you are wasting your money. Like Samdweezle said, get it for the HP and tell yourself mileage gain is a benefit. And if you don't need extra HP....then I wouldn't waste your money.

I've been testing mileage tunes this week.

Using EFI Live and changing EGR, turbo vane position, injection timing, as well as changing when the torque converter locks has really opened my eyes to the real MPG potential.

Went from 14-15mpg in the city to 17+mpg city driving. This is with only the first test. I'll be fine tuning and testing again.
