2015 6.7 platinum. Need some input on the best programmer or chip for fuel mileage And towing. I need one that doesn't leave foot prints because it has the extended warranty.

As of right now it has a flash pack by super chip, "recommended by ford" Not impressed.

Also what is everyone getting for fuel mileage? And after how many miles does the fuel mileage start getting better. As of now it has 14,000 and it's finally starting to get a better.

Thank you guys for all the input in advance.

 

Also I was told there is a programmer that makes it where you don't have to use the DEF. Anyone ever herd of that?

 

If you use a programmer that works with a Delete, Then the DEF is gone.
But you will have to drive a lot to save enough in fuel mileage to cover the $1500-$2000 cost of the programmer and delete. If the programmer bumps you from 15 mpg to 17 mpg, that would take over 100,000 miles pay back
the cost of a $2000 delete kit/programmer before you save any money. Pretty much any chip you install will leave a signature. I've had the mechanics tell me that they can tell as soon as they pull the heads and see the burn patterns on the pistons tops whether the truck ever had a programmer or not, because of the increased flow from the injectors. So even if you reflash or clean your PCM, mechanics will probably spot the side effects of a programmer.

I also don't see an increase in fuel mileage for breaking in. Current engines are built to such exact tolerances, there is not much break in. My 2011 with 145,000 miles never improved. In fact the best mileage I ever got, was during the first week I owned it. My current 2015 is now at 20,000 miles and still getting the same mileage. It's not like the diesel of old that needed 10,000 to 15,000 miles to break in.

Now I do believe we get past the "New Truck" stage and quit goosing it to feel the power and become a little more concerned about operating cost and a little lighter on our go pedal with time. A person might see his fuel mileage improve because he is trying to go easy on his wallet.

If you want to play with your truck. If you have money to spend. Get a programmer and a delete kit. You will be slightly faster,More HP and Torque than the rest of us. You engine probably will last longer because you won't have the EGR dumping carbon back inside. But don't buy it because you think you will save money on fuel mileage or that Ford will not notice it when warranty work is needed.

Save the parts you take off. You may need to reinstall them when you sell or trade the truck. Some dealers in areas with emission testing will not accept a deleted truck in trade.

 

Agree 100% with this statement! Also, you mentioned towing, NEVER tow with any tuned truck that is not in the stock setting. You will tear up the transmission quickly. Several on here over the last few years have found out the hard way.

Link to a post you mind find helpful. Most tuners have towing specific tunes that many of us use all the time. I've been tuned for over 50k miles and tow heavy trailers frequently on a towing tune. Now that I've typed that, I will blow up tomorrow, lol.

I would not recommend anyone tuning/deleting/modifying their truck without extensive research and getting familiar with how to do it and beyond basic knowledge and skills working on a 6.7 engine. You better feel comfortable getting your hands dirty

 

I'm still in the fog from the cough medicine last night. What I meant to say and what I typed are two totally different things. Andre is correct. There are GOOD programmers out there that have great TOW tunes that work as they should. Avoid the cheaper "one tune fits all" tuners as they can cost you thousands.

 

this...
I haven't seen any transmission failures from towing tuned, but I'm sure others have. What I have heard of is a lot of turbos going pop goes the weasel.

 

I have seen several around here that have severely damaged the transmissions from towing heavy 5ers up and down the interstates and up into the mountains. It started in the 6.4s and found its way to the 6.7s. The primary one that has caused these is tearing up the torque converters. I've read on other forums that this "Big Name" mfr tells you to tow only in the stock setting but sells the package with a "tow" tune. Now, many of the shops around here will not use their programmers anymore.

 

My own input is that if you keep all the emissions equipment on the truck as stock, do NOT add a programmer. The DPF and other emissions equipment is very sensitive to changes due to programmers, and they don't react well, especially if you're towing.


The emissions equipment is designed to function under certain parameters. Programmers alter those parameters, at times beyond what they are designed for, which can cause premature failure or other issues.

Ford doesn't recommend any programmer for these engines. The dealer on the other hand may have recommended it because they sell it. But that has nothing to do with Ford.
