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

Care to elaborate on the can of worms comment?

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?

If you're going to tune it yourself then I wouldn't bother with blackbear, there isn't anything to unlock you just need a tuning suite like efilive or hptuners.

And 96k1500, if you go to supercharged's thread on his whipple dually thread you can see his concerns and then my response to those.

surprise, az
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.

Blacked the flares, I like it; but instead of trying to paint these up I'll just grab some OEM style flares off Ebay or something, I need to get headlights/lamps/corner lenses ordered as well as a smoothie diesel bumper and maybe a GMC grille like I stated in another thread.

Not the greatest, it being humid as hell made it difficult to get a good clean coat, and I literally ran out of plastidip on the last fender, but I got it done and got the tape and everything pulled up 5 minutes before it piss poured rain. So it's a victory in my books,

Ah, well.
I need to quit finding motivation at the end of the day to do things.

Decided at 7:40 in the evening that now would be a good time to service the truck, so I ran into Autozone, got a K&N service kit and some MAF cleaner; tore into my truck and had everything cleaned and reassembled by 9:02, letting everything dry took the longest. It was probably past time for this seeing as how the filter was full of dust, pollen, and leafs as I was banging it out, and then muddy brown after applying the cleaner and hosing it out. MAF wasn't much better, dusty as hell and had a few little stems and **** in the screen.

It runs, SO much better now, throttle response is instant,

Supercharged is spot on with this. I would not attempted it without tuning software.
