Yes, they both came in one box. One big one and one small one. I ordered from dieselfiltersonline.com or something like that.

OK, I ran it like I stole it this morning and it ran great, but I'm sure this is just because I didn't keep it in the studdering RPM range. I would cruise a little on the highway and it would still do the same thing.
I still want to replace the fuel filters and pull and clean the EGR. Hopefully one of those takes care of it.

Mark,
Sage advice --- never believe that unplugging EGR solves anything.
Suppose a valve is stuck open.
By being stuck open, if it went into relearn (from a computer reset) it learns the new "closed" position when in fact it is open.
Trouble goes from there as EGR flow is never right.
I am with you on the issue that EGR system should be properly working, not deleted.

The enchilada
dbm04F250,
The low power and lag problem could be a result of the sevice "Tech" not performing the VGT re-learn strategy after flashing the computer. Here is the strategy you can perform it.
KAM (keep-alive-memory) reset & VGT learn procedure
1. Drive the truck until the engine and transmission have reached normal operating temperature.
(The VGT learn procedure requires that the oil and coolant temperatures be at normal operating temperature)
2. Flash truck back to stock (Only need to do this if running a tuner or module)
3. Turn on the headlights
4. Disconnect both batteries
5. Short out + to - battery cables to each other (Make sure both batteries are disconnected before doing this).
6. Let truck sit like this for 10-minutes
7. Turn off the headlights.
8. Re-connect batteries
9. Cycle the key to the run position twice. Pause in the “ON” position each time until the wait to start lamp goes out (minimum 5-seconds) and pause in the “OFF” position each time for 10-seconds to be sure the PCM has "gone to sleep".
10. Start the truck and let it idle for a minimum of 5-minutes at normal operating temperature. This allows the PCM to learn the EGR valve closed position value. Also you will likely hear the turbo pitch change several times during this period as the PCM learns the necessary duty cycles for accurate VGT control.
11. Complete the road test Drive Cycle:
15 miles of mixed driving (*should* be enough in most cases) to allow the PCM to "re-learn" its adaptive strategy.
Note: Anytime the batteries are disconnected, the PCM will throw the P1000 code until the “Drive Cycle” is completed.
As for the Tow/Haul mode, the transmission must re-learn your driving style and loads hauled again as this was cleared when the truck was re-flashed.
Hope this helps

Enjoy ---
Just an observation.
Forums are full of people who love to jump to conclusion that inevitably involve putting on some expensive part, mod, or custom upgrade.
I have fixed many issues on here with simple things that cost next to nothing.
Had I listened to the advice I initially got on forums when I bought the truck, I would be $20,000 into mods, upgrades, etc. and still not be happy.
I operate my 6.0 stock with very few upgrades, and no custom mods, tunes, etc.
It drives perfect, fine, and is RELIABLE.
I appreciate that you are trying to not let the 6.0 bankrupt you.
Beware of the high priced "fixes" that often don't fix anything.
Things that many people don't want to hear on here.

Yeah, with a baby on the way, I'm walking a thin line between getting this thing smoothed out as cheaply as possible. A lot of guys on here are all about mods and I enjoy reading their posts, but I'm not one of those guys. If I can get an extra 20HP, that's awesome, but I'm more worried about fuel econonmy and reliability. I'm 28 and I want this thing to be hauling my family around when I'm 38. I would hope these trucks can do it if they're taken care of.
I'll try cleaning the EGR and hopefully get the fuel filters replaced soon since these are cheap and should be done anyway. We'll go from there.

Don't even think of the 20hp.
The risk you run is huge --- if your goal is reliability.
There are guys here getting 500hp reliably and inexpensively --- but they are people who really know their s.... and NEED the power for a paid, commercial application and can afford the higher costs.
Lets get this thing running reliably for you as the first goal.
Then step by step, go for the reliability mods --- most of which are cheap and proven.
Don't go down the garden path of throwing parts at this thing.
If it ain't broke... don't fix it.
Does IT stand for Info Tech?
If so, you are going to be very lonely in here.
