Since buying my 2016 in the spring of 2021 I have been here trying to learn as much as I can about owning my first diesel. With that said in the following, I am referring to 6.7 motors specifically but this is also a general question of all modifications.

Since that time I have toyed with the idea of changing from stock but in my observations it seems that most posts looking for help or having issues with their truck running are trucks that have been modified in one way or another.

Does modifying a truck lead to more problems than leaving stock?

Two things:
1. "modifying" is a broad swipe and not specific enough to answer
2. Take a count of how many positive vs negative reviews you read, once you realize the count is swayed to negative because they complain more, then start to wonder if the issue is an installation issue or a larger issue with the truck.

I believe you are trying to refer "modifying" to a specific modification without mentioning said modification. That being said on the internet you are mostly going to hear about the problems and not the hundreds of thousands not having issues. Most of the issues people have is once you mod it then you also have some more "fun" accessed with the truck and mostly, subconsciously sometimes and consciously other times, "beat on" their trucks more. Same as most things if you take care of your things you shouldn't have many issues.

Well some modifications are frowned upon, others I see are with tunes and then transmission problems after said modifications.
I realize people post when there are problems but there doesn鈥檛 seem to be a fraction of the problems posted on stock vehicles.

in my experiance the aftermarket go fast items are usually not as reliable as OEM ( but not always)
then you add in non profesional install practices ( scotch locks , rubber band,duct tape for example and
then you are bound to be stranded by your "improvment"

so I suggest pick the desired " modification" research it online and if it passes that test then install it like it was going in an aiplane and skip any hackery shortcuts

The answer to your question is as broad as the question itself. You have to take into account the type of modification, the quality of parts used, the ability of who did the modification, the intended result, and how the vehicle is actually used. With some mods come an increase in required maintenance. Others limit how the vehicle can be used. For example, if you modify your truck to be used specifically off-road and you then try driving it on the street you'll gonna find it's not as reliable as it was before. There is no cut and dried answer to your question.

I agree with everyone above. However, when you go to diagnose an issue, the mods you install tend to be a "well, you have x,y,z mods..." especially when it comes to vehicles that were tuned for the mods. It's not necessarily more difficult to diagnose the problems after mods, but it can add another level of troubleshooting to make sure the mods you did weren't the cause of the issue.

I didn't mod my 15 6.7 because in my experience with other cars they don't make things better. Sometimes it cost more money to fix what I was trying to do. My truck has had the DEF heater go out and the DEF nozzle go bad but that's about it. My truck has been reliable since day one with just a couple issues. I tow with mine and have around 40,000 miles towing and around 87,000 miles on the truck. I am however in the process of replacing the lighting on the truck with LED lights. These headlights dont cut it when driving at night. I am getting mine at WWW.headlightrevolution.com They test them there and I am pleased with them so far.

I think you鈥檒l find experiences and outcomes will be different for everyone. My truck has identified as a 鈥70s model for about 100,000 miles now and it feels stronger today than ever. The only issues I have with my truck is front end steering and suspension components going bad but that鈥檚 just the nature of a heavy truck with a solid front axle. I鈥檓 still using the stock turbo and transmission has yet to be rebuilt at nearly 200,000 miles. Ford really out done themselves with the 6.7L.

Power stroke Tech Talk on YouTube recently previewed a 2013 truck that had over 1.3 million miles. The owner has gone through a couple transmissions and a couple turbos but that鈥檚 really it. These trucks outperform most other comparable trucks on the market in so many ways that it鈥檚 almost stupid to buy a Chevy or Dodge.

In fact, I had a Dodge guy tell me that 鈥渄espite Ford being the #1 seller of trucks, there are more Rams on the highway鈥. My response was simple鈥 鈥渢hat explains why I see more Rams than Fords on the side of the road, I suppose鈥.

He wasn鈥檛 a happy camper hearing that. But it鈥檚 true. I drive a lot on the east coast. I鈥檝e put 20,000 miles on my truck in 4 months and all I see pulled over are Rams.

Anyhow鈥 modifying a truck is not always bad so long as you know what you鈥檙e doing to the truck and it fits the parameters of the trucks purpose. Would I throw a stage 4 turbo on my truck and attempt to haul my fiver? Nope.
