Good question. 411 is a can of worms with the 454. You'd be datalogging back and forth to get it right.

Sounds like he has no experience, swapping a 411 pcm on a 454 truck is no different than swapping to a 350 truck, repin the harness and get it tuned to the truck

So would a mail order tuner like Black Bear be able to unlock and reprogram the PCM to a base line tune for the 454, and then tune it myself from there?

Your "get it tuned" comment is all I needed to hear to know your level of tuning ability.
Seeing as I have no tuning programs no I don't tune, however the swap is the same between a 350 and 454, and any shop that does tune can tune it just the same as for any other application
Well seeing how I do have a tuning program and have tuned about a dozen cars, I can say they're not the same. Sure they may pin right up, but no 454 ever came from the factory in North America with a 411 so no domestic base tunes to pick from. So just change injector constants and cylinder volume and go! Not exactly. As Cristian Steffen can attest it's not as bad as the worst case scenario I had envisioned, but it is still a good deal more involved that pinning it to a 350, hitting the key, and rolling down the road with a nice clean tune. 350/411 is a viable mail order combo but 454/411 would require 2 way communication with the tuner and likely some datalogs to clean things up, i.e. can of worms.
