Your facts are not 100%. I never expected to get good mpg with this truck but it is much better than a 5.4. Larger exhaust system has added problems also. Removing the cat has bad effect on turbo! Tuner will blow head gasket. If the larger exhaust improved mpg Ford would have changed it years ago. I lifted my truck and put larger tires on it and I have to say it is much better than stock. But because of roll over problems trucks and suv's are low to the ground. It is easy to say that every action has a reaction. My trans is a little warmer now but I get the trans fluid changed every 15,000 miles for $130.00 each time that is worth the cost. Oh I almost forgot the after market air filters every body paid $$$$ for studies show the the stock air filter was better! Yes I purchased a K&N for my 5.4 no change in HP , MPG or anything. But it had a good sound. If you boost HP on a 6.0 you must be willing to pay for it down the road. I would rather put lower gears in than all of that add on HP stuff. You all better do some research on the problems with quick HP fix. Why is it that your dealer will void your warranty if you use a tuner? Why can't you purchase a tuner at your local ford dealer? Facts Facts Facts not sarcastic comments. If you can show me proof that a tuner and exhaust will improve the longevity of my truck than I will buy one. I removed my muffler and it sounds good but there was no change in EGT. I pull a trailer and had one installed. I was going to purchase a tuner so I had the gauge installed. Just tired of the B%^^ S(*^ and just decided to put it on hold until I see some positive results
For sure EGR coolers fail and cause LOTS of problems. Eliminating BOTH the EGR valve and cooler will certainly improve reliability as well as guarantee you do not get coolant leaks into the engine from a failed EGR cooler. This is a HUGE plus. A custom tuner will then get you better performance with a deleted EGR valve than the stock system that has a deleted EGR valve - because the program takes this into consideration. With tuners you also get improved shift performance. Doing all these things individually is only partially effective - as a package, reliability AND performance (acceleration, HP, towing capability) improve. Fuel economy may or may not improve - depends on too many factors (your driving style, your purchased fuel, accuracy/reliability of all your trucks sensors, your diligence with preventative maintenance items, weather conditions, etc).
Just because Ford does not sell tuners doesn't mean that they can not be used reliably. Many people do have reliable trucks with them. The main consideration is to "know your trucks limitations". Then you either drive within these limitations OR get more mods to eliminate the limitations.
Lastly - Maximum4X4 and kw5413 are giving you the straight scoop and have great advice which comes from MUCH experience.

There are so many variations in hardware, software and driving conditions that would simply produce different results for what someone else has seen and what you'd expect. Thats just the way it is.
I know of no two vehicals that are the same. If you want hardcore results, become good friends with a shop that has a dyno, start mixing and matching different conditions, then you may see what runs best for your application. Even then your driving style may change that.
Hope you don't consider this B%^^ S(*^ feedback. I consider it more or less common sense but you'd have to see dyno results enough to recognize it.
First off, this is a 6.0 diesel forum. The comments about comparing the mods on a 5.4 to the mods on a 6.0 are apples to oranges. The egr cooler delete is one of the best mods I have EVER done. THERE IS DEFINATELY MORE POWER. I called around on the 5.4 before asking about mods and everyone told me dont waste my money, there will only be headaches because there is only so much power in the motor and the new 5.4 is harnessing just about all of it stock.
Want better fuel economy? Loose the lift and put the stock tires back on, that will get ya a mile or two
And it doesn't cost ya a thing, just a little of your time
My facts are always dead on. Custom tuning is what you want, if you want your heads shot through the hood you need head studs. Custom tuning has many variations, that is why it is custom. The best transmission files will lower your transmission temps because you are locking the torque converter and not creating heat...Ford has a good trans, custom tuning makes it better.
If you are going to lift your truck and add bigger tires, gear ratios must be kept in mind. Not sure why your worried about a roll over after lifting your truck, the center of gravity is higher. Some people should not drive a lifted vehicle if they do not understand the basic effects of center of gravity. The automakers build vehicles with a low center of gravity, the same way McDonald's can not serve hot coffee.
You won't find many of us recommending an after-market air filter like K&N.
My 2003 has an after market exhaust with a 3.5 down pipe, I never lost low end power. Biggest is not always better, the debate goes on. A 4 inch down pipe losses some low end but has a lower exhaust temp over the 3.5 down pipe. Either way the end result is lower temps.
Ford builds a vehicle so every person can drive one. The vehicle has to meet emission standards and safety regulations. What you do to personalize a vehicle is your own right as an owner.
I firmly believe in PAY to PLAY.....I do not support running to Ford to fix what I broke.
Thank you you made more sense than most replays. I do not mean to come accost in a bad way I just had to be honest. You answered my question. I looked at Modules and tuners and now I have to find out about custom tunes. Good lesson thank you.
Before I purchased anything else I wanted to make sure I did not make things worse like I did with my F250 5.4. I was comparing the non effective performance that I got with my chip and exhaust so I would not waste my money again. I unplugged my EGR Valve and people said wow what a difference I had none in fact I lost MPG. Plus it made more noise I liked that! The MPG that people say they get is impossible 20 plus miles around town Come On! I did not expect to get the good MPG I get with it lifted and 35" tires and I can't complain with the piss pore fuel the government makes us use. I asked for facts not unjustified opinions. I got some good results and thank you for your time and effort.
For future reference it is important...with the 6.0....to state the engine build date or at least the MY of your vehicle. If one doesn't take the time to do so the responders likely won't take the time to pull up your profile to check what you might have. Makes it a lot easier to receive specific recommendations. Each engine build date range had specific issues...especially in regard to the '03 & '04 MY. If you don't tell us what you have you get generic answers at best.
Responders typically won't invest much more time / detail in the answers than original posters do in the questions.
A little bit of searching and a lot of reading would provide many answers. In the case of the '05 6.0s it was 50/50 on whether good results would be realized by disabling the EGR Valve.
In addition, if anyone is looking for better MPG as a priority (in regards to the EGR Valve) they are likely pissing up a rope. Any enhanced MPG would only be a bi-product. The primary reason should be to keep trash from being re-introduced to the engine. Thereby saving down time, expense, and possible tows.
I hope this info helps.

Bro, bottom line, sometimes there are no black and white answers. I pulled my EGR plug at about 4,000 miles, and it hasn't been in since. Milage remained about the same, power remained to feel the same. I use the words about and feel, because I didn't have a bunch of data aquisition devices hooked up and can't convey concise data. Neither can anyone I know. The piece of mind I get by not having exhaust gasses re-circulated back into the intake is priceless. Run the truck, enjoy the truck, work the truck. When/if there is a problem, come here for the advice of those who may have been there before. Everyone has opinions, that is why there are multiple manufacturers, multiple options, multiple colors available. Not everything is black and white.

Your truck was built on July/20/2004 the engine build date is located on the drivers side valve cover FICM (Fuel Injection Control Module) where it will have a sticker, that is the one you are looking for.
Now to see this sticker, really a pain in the arse stand on your head beside the truck with a flashlight and look around the brake booster...
