Hi Everyone. Well, after 15 years the RV-Dreams Community Forum is coming to an end. Since it began in August 2005, we've had 58 Million page views, 124,000 posts, and we've spent about $15,000 to keep this valuable resource for RVers free and open. But since we are now off the road and have settled down for the next chapter of our lives, we are taking the Forum down effective June 30, 2021. It has been a tough decision, but it is now time.
We want to thank all of our members for their participation and input over the years, and we want to especially thank those that have acted as Moderators for us during our amazing journey living and traveling in our RV and growing the RV-Dreams Family. We will be forever proud to have been founders of this Forum and to have been supported by such a wonderful community. Thank you all!!
I have a 2009 Dodge 3500 with a cummins turbo diesel in it. I am looking to improve mileage. The truck has plenty of power and everything, so I was wondering if anyone is using those engine tuners I see advertised in the magazines? And if so what are you using? I plan on adding a cold air intake also. According to the ads they say those improve mileage and horsepower too. Maybe evan a freeier flowing exhaust. But the first two things I can do on my own.

While I'm not an expert on the diesel engine "tunes," from what I've read on other forums, the only ones that seem to be doing it are those that won't be doing that much towing. Some of those that do tow say that they would never "chip" their engines for any reason. I'm not really a mechanic of any kind, I've always been hesitant about doing anything that hasn't been recommended by the manufacturer. No more than I know, I prefer to defer to those a lot more knowledgeable, in this case, the engineers that designed the things.

May I offer this perspective:First, the manufactures do “de-rate” the engines some from their maximum performance capabilities for both warranty and EPA reasons.Common knowledge They do “protect” the total drive train, in so many words, with the computer (we’re talking current engines now, not engines of 15 years ago) such that excessive EGT, TIT, torque and the like are not exceeded.
IF, and that is the key word, they could “tune” an engine to give you more MPGs towing and solo and they could meet warranty limits, i.e. reliability / longevity and EPA regulations why wouldn’t they?Simple answer, they would.This is a marathon equation for reliability. Not a one day sprint on the race track so to speak.
Now, can you alter the tune and increase power some or fuel economy some?Yes, but it is still chemistry and physics.You can’t do both or they already would have.
In the case of a modern diesel engine doesn’t it make sense, for long term reliability and dependability, to allow the people who designed the engine to have the last word with the safety protections built into the engine?I think that is a valid question.
Now, can you make changes that might improve one aspect of the MPG vs. torque vs. HP equation a bit?Maybe.But at what potential risk ($$) to the engine or transmission; and at what real cost savings?
Just saying -My perspective.These things are very expensive to repair or replace.

I put a chip in my 2003 Dodge. Boy did it make a difference in power and fuel economy. I believe it also was the reason I had to replace the transmission. Now those Dodge's weren't known for reliable tranny's any way, so who's to know for sure.
A great source of information for Dodge/Ram owners who like to play with their trucks is the Turbo Diesel Register (www.turbodieselregister.com/). From what I've read, I wouldn't modify your engine, including the air intake and exhaust systems. If you do decide to do the cold air intake, I would go with a dry filter like the Airaid cold air intake system. It's easy to over oil the oiled air filters, making them less effective and adding an oil mist to the air intake than can affect some of the engine's sensors. - John

My point exactly.More to this equation than just the engine.
Another great place is the Dodge Owners Forum. For an '09, H&S makes a great setup that will help alot. Different model years respond differently to different tuners. The 48re is the known weak point in the drive line. A few parts in it though will make it a great transmission for towing.
