No one said nothing would ever break turning up the pump. It was mentioned that the power was set to where it was at the factory because of warranty issues... implying things may not last as long with more power.
As I see it, there are two types of people in this forum. There are the ones who bought a Dodge diesel to have a reliable vehicle built strong enough with enough power from the factory to take care of the jobs they need done from towing to plowing to hauling and still get decent mileage and still be in one piece after several hunderd thousand miles. All the more power to them, leave it stock, it will save you a lot of headaches and it will still do what you need it to. I hold nothing against you.
Then there are the people who bought a Dodge diesel knowing the amount of aftermarket performance parts that are made for them, knowing the easy power they can make, knowing that with some tools and a little bit of know how they can make 3 tons of metal move faster than anyone would ever imagine could be done with gasoline motors. The phrase is routinely uttered on here "you are your own warranty station. " It is, and should be more than clear that when changing anything from stock, expecially adding horsepower... . some things can and WILL break. Before breaking that first bolt loose on the AFC housing on the fuel pump, before writing the check for those high flow injectors, before asking anyone about how to make power, before searching the internet for quick answers... anyone with half a brain knows that something can and will go wrong at some point or another. More so, it is also know that the amount of things that go wrong and break will be directly related to the amount of power increase and also the amount that the power is used. This is in fact common knowledge.
It is also known that pushing the accelerator pedal futher down more often burns through more fuel, and thus it is also known that doing anything that increases the amount of fuel flow when you push the accelerator pedal down further also has the POTENTIAL to burn through more fuel than the previous setting. This is once again, common knowledge.
I bought my truck almost 4 years ago now. In that time I have cranked everything my wallet would allow me to crank. I've driven it like a sports car, I've driven it like a baja truck, I've driven it like a mudder truck, I've driven it like a trail truck, I've driven it like a rock crawler, and I've hauled with it more than the springs should ever hold, and I've towed with it more than my last transmission rebuild shop told me I should. I have baja'd over 5 foot tall snow piles at 40mph, I've jumped "speed humps" at 80mph, I've raced everything from a bmw to vw tdi, I've towed my other truck, towed moving trailers, towed cars, I've hauled 4000lbs of decorative stone in the bed, I've pulled dozens of cars out of ditches for fun, and I've buried my truck to the diffs in mud. I have a graveyard of broken parts consisting of 3 turbos, 4 transmissions, 2 sets of tie rod ends, 3 drag links, 6 u-joints, 2 driveshaft yokes, 5 steering gears, 3 steering gear mounting plates, a radiator, a flex plate, hundreds of dollars worth of blown up exhaust pipe, hundreds of dollars of leaked oil/antifreeze/transmission fluid/ps fluid... I've had a wheel fall off, dropped a driveshaft on the road, had my steering break loose, have numerous times had exhaust leaks into the cab, my truck doesn't shut down without hitting the manual shutdown lever, I have an oil leak, a coolant leak, and a transmission fluid leak, I have to buy a new set of tires every year, add to all this I have 20 driving related tickets, 19 of which are since I bought this truck.
All this (except maybe the tickets) are things I expected before I made any attempt to change anything on the truck. For that matter, I expected some of these when I bought a 12 year old (at the time) farm truck that had seen it's share of abuse by a farmer who expected a lot of out it and thats what he got. It was bone stock except for air bag suspension in the rear, a gooseneck hitch in the bed, and a trailer brake that wasn't exactly hooked up right. I knew going in that things would break and they did. As did all of us expect that it wouldn't always go exactly as planned. As does anyone with any vehicle with any motor and any drivetrain that has made any attempt to "supe it up" "trick it out" or "pimp my ride. "
We are the other type of person on this forum. We are the Tim Taylors always looking for more power (arr arr arr), we want to be faster than the guy next to use, bigger than the guy stuck in the mud hole, and louder than our buddies diesel truck with a custom exhaust and a cranked up pump. Some of us have money, and most of us have ingenuity.
We don't hate you for leaving your truck stock. We respect you for your contentment, restraint, and reserve. We envy you for the money you save on parts. We appreciate you picking up the slack showing how reliable these trucks really are because all our friends an co workers will never believe us that its our own fault they break all the time. We are happy to share this forum with you and to have your wisedom shared in this pool of knowledge with our own.
But the forum was titled "turning up the pump today, a few questions first" and not "should I or should I not turn up my pump. " There was no reason to come in here and start a fire fight over whats going to happen when you turn up the pump. Both sides know what will happen. One side is just more willing to accept the outcome than the other. Try going to a drag car forum, a rock crawler forum, or a mud truck forum and telling them they should leave their vehicle stock and insulting their intelligence for wanting to change it. An off-the-lot jeep won't climb rocks, an off-the-lot mustang won't run 10s, and an off-the-lot pickup won't make it through a mudhole. So we change them. That's what sets us apart and thats where the glory is in winning the drag race, or the mud run, or the hill climb, because we built it like that, not cause we bought it like that.
This forum is a wonderful place where both type can share knowledge and experience from both sides of the fence over a common gathering of a particular type of vehicle with a particular engine. This post though, is directed toward the second type of people, the question was asked of the second type of people, and the responses should have been from the second type of people or at least with respect to the second type of people. We want you to share your knowledge of the autmotive industry and of our trucks with us, but if all you're planning on doing is shooting down our ideals, there are plenty other intelligent people on here running twice the stock horsepower that can point us in the right direction and warn us of what might break FROM THEIR OWN EXPERIENCE. So you worked for whoever doing whatever where ever, where some engineer told you that this or that is the tested limit of any given part. Big whoop. There's a million miles of experimentation reading this post as you are. If you have any bit of pertinant information, keeping in mind that no matter what someone with a stock truck says about what will happen with a non-stock truck, his fuel pump will be turned up soon, the please, feel free to post. If not, I'm sure there is another post somewhere on here where someone with a little more reserve and a little less... curiosity... is wondering how to do their first brake job.
Attention: TDR Forum Junkies 
Call me a moron if you like. That old dog (ext cab 2wd stock auto) got well into the 16s in the quarter with ONLY pump tinkering.
), or were just fixing up a previous owner's mistakes/ neglect/ nightmare (there's a reason some of them go for under a grand). But, I have had the trucks in the middle (91 4x2 comes to mind) that were slightly turned up, maybe a 3. 5" exhaust with a performance air filter, that had as much power as a then new truck (2002), yet got much better mileage (24-25). I personally have come back around to that stage- I want more than 160hp/ 400tq- maybe 230/600- but am focusing more on economy and longevity than beating that Duramax with the triple stacked chips and Stage 3 injectors, etc, etc. I'll leave that to the ones like TSC. If I can get 18-20MPG with a fully loaded shoeing rig that'll go another 500K above the 290K on it now, I'll be tickled. 
. Just ease up on the guy, he has a right to his opinion.
