Cons of doing a DPF delete on a diesel truck

On what truck? I'm wanting to do mine but I've always been curious whether it hurts/helps in the long run to just do away with that stuff.

Can someone explain studs to me like I'm a 5 yr old

Removing the factory headstuds and replacing them with stronger, aftermarket alternatives. Thus reducing the risk of the factory headstuds stretching and blowing a headgasket.

Definitely makes more power than I'll ever need. My only reason for even looking into it would be added mileage and increased longevity. A clogged EGR just sounds like a horrible idea in the long run.

On a side note one of the intercooler charge pipes on the 6.7 is made of plastic, apparently it's known to break down over time and spontaneously explode. A few companies make a metal replacement(~$300). Luckily mine happened as I was merging on i10 in front of Courtesy Ford. So common Courtesy kept the pieces in stock and the tech told me they replace several a week. There's never a sign of when it'll happen, it just does. I don't want next time to be in the middle of nowhere.

I'm not overly familiar with how the tunes are set up, but tuning up while towing is probably going to put boost pressure pretty high which may or may not lead to early head gasket failure.

This is touchy to do right. People like to pull tons of power out of those motors because they're capable of doing it. It can push tons of fuel.

For longevity and efficiency you would want to tune down if anything. There's a reason heavy duty trucks come with more moderate power curves.

I'm sure there's plenty of information available on what you can safely do on factory hardware. I don't imagine it's too far above what you get from the factory though. Your key things are intake manifold pressure, intake temperature, and egt.

Fa sho. There is no reason to be driving around with 600hp at the wheels

There is also no reason to be pulling a D5 70mph and attaining 62psi of boost on a basically stock engine

At max, I'd go +150hp. I was running around with +275hp and +315hp at the wheels. Stupidity

My fuel mileage did go from....I think around 12mpg to 24mpg on the highway, but that was offset by the $30k I spent on the perpetual engine problems :banghead:

Good custom tunes will eliminate almost all black smoke.

All you need for the 6.7 is a dpf delete pipe, sct or H&S tuner, custom tunes, egr delete or egr block. The stock bolts are more than adequate for stock fuel.

I got a quote for $1000 for everything. I'll be deleting mine soon and running a very mild tune. Keep in mind, the 11-14 turbos love to burn up with moderate to high boost. That's a $3000 bill for a 15 retrofit turbo.

Where'd you get a quote from? I haven't given this any serious consideration since I bought the truck new in 2012. Back then I remember it being ~$2500 or so. If, and that's a big if, I ever do it my route would likely be an intake, exhaust(though probably not necessary), EGR delete(or blockoff plate, not sure it matters), and very mild tunes. It's an 8000lb 4x4 brick of a truck, I don't need it to go faster, I certainly don't need it to accelerate any harder while towing a trailer. I just want better mileage, and piece of mind to know it'll last 10 years. Modern diesels scare the shite out of me.

Words can not express my jealousy. When I bought my Ford I almost went look at the Dodge lot, mainly because I really wanted a manual tranny but ended up just sticking with the Ford. 3 years later I still want a manual tranny and I'm constantly impressed by my dad's 6.7 Cummins getting 20+ mpg where I'd get 13.
