Any advice??

A little over a month ago I was reading on here about a re-flash that would help with rough running with a cold engine. My truck did that indeed but for only about 5 miles. After that distance it ran flawless with a ton of power. If it wouldn't have shaked the truck so much I would have lived with it. Driving home after spending $85.00 I didn't notice anything but it was warm and on the stock tune. The next day I started it cold to see how it ran. She idles perfect but once on the road it still bucked. The difference this time is it continued to buck for over half an hour. I also detected a mis while excellerating. No miss's before the re-flash. The harder I pushed the peddle the more pronounced the mis. I called the dealer asking if they could have installed the wrong flash or something like that and they said no. They want me to bring it in for a series of tests at my cost (of course). If the truck ran bad to begin with once warm I would have no problem paying for the diagnosis. But I'm pissed seeing this only started after they re-flashed it. Any advice for a frustrated truck owner with a now sick 6.0???

Call 911 and have your State police meet you at the dealer. You shouldn't have to pay any thing more for a bad flash. It sounds to me like your flash did NOT take. They need to reflash it...talk to the service manager asap...if no luck...up the chain...keep asking who the next person's boss is until they get it right. Supposed to fix it not break it. Damn...

The dealer claims you can't install a bad flash.........

Google it...he's on crack...anytime your moving those Binary codes around 0's an 1's...anything can happen...there have been faulty flashes...just ask around or search these forums and the internet....seriously though...if your dealer said that, then make him put it writing and ask the Dealer owner to sign it...(bet that wouldn't happen) then take your truch to the nearest dealer (other than the moronic service team you just left)...Tell them the story and ask them to install the latest flash...besides if the current dealer stands by their flash...then ask them to just re-do it...not like its costing them anything other than the potential loss of a customer and everyone you speak with on a daily basis....lol

Is driving it the only way to tell if the flash is any good?

You probably did this, but I have always been told to set the tuner back to stock before getting a flash applied. Many folks did not do this thnking that Ford was fixing something specific (and they would not update the programming because that was not requested) only to find out that Ford did apply the flash - and things got a little scrambled.

Yes, I put it back to stock before I took it in.
