When I go to the Sierras I have no cold start issues in the 20's. That is unplugged with the truck parked in the woods. I let it warm up for about 1 min. in hi idle mode and go, driving conservatively till she's warmed up.

I just bought a 2004 with the 6.0 L and have a couple of questions. I test drove it in the afternoon and it ran great, almost can't feel it idle with more power than I could shake a stick at.
Well, the next morning I started it, after waiting for the glow plug, and it sounded like !$%Q@$%. I let it idle for a minute and then crawled through our neighborhood. I think I would have had more power on my bicycle. It idled high, would not shift and I had a hard time getting over 10 mph. After a few minutes it got better but took probably 10 minutes to feel the way it did when I test drove it.
Would a reflash correct some of this?

Aftermarket is a real no no if you read alot of the information here.
If do not want to get from dealer can get from here:
www.dieselfiltersonline.com
Would not want to do anything with the new Prime Guard Filters they have listed. Made in China. JMO
Donaldson makes the OEM air and Racor makes OEM fuel and oil.
Hope all works out well.

If your Ford Dealership did the work...I'd say with 99% certainty your safe they used the best filters for your truck. Sounds like a re-flash should help since all the other minor things have been covered.

I had my truck at dealership (one that is 25 miles from my normal dealer) to have transmission service. While it was there they fixed a couple of oil leaks they found while it was on the rack. The dealer owner actually picked my vehicle up for me and drove to dealership. He noticed that it ran rough with cold start and that it had buzz flash. He said that he had techs reflash while it was there. This evening (engine still warm) it started much quicker. The lieometer was on the dash read 19.0. I normally don't have it displayed as I drive so I guess the dealer changed it while he drove it back to my office. I was curiously happy to see the 19.0 because typically that drive would show 15-16 on the display. So we'll see how it starts in the morning for cold start. And when I shut it off this evening, the buzz was gone.

So far I've been pretty happy with the new flash, Not withstanding any long-term issues I think they did a pretty good job, I've got an XLT with no MPG readings in the dash and I haven't gone through a full tank yet since the flash so I can't give any concrete MPG numbers yet.

I am a little lost. I have an SCT with Innovative tunes that was running on my 04 truck. The strategy on the truck is VXBC9. It was running great before the oil cooler disaster. Please help me to understand if I should be reflashing and if can run my SCT as is. Is my current flash the one that is hard on FICM's? I want to start out right on this new engine. Keep in mind the new engine is egr system gone and the ARP studs are holding down the heads. An Edge insight is watching over the vitals. The SCT tune I would like to run is a plus 50 hp.
Thanks for all the help I have been getting here.
