Changing my mind - 6.0 into 1997?

I've been studying swapping a 6.0/4L80 into my 1997 RCSB 4.3 for several years. It's not my daily driver, just going to be a fun toy.

I had originally planned on following closely to the "Lisa's Tahoe" build from Street and Performance, but now as I've read more and more on this site, I'm thinking that keeping the V6 computer may not be the way to go.

What is the best way to convert to the LS? Keep both computers or ditch everything but the V6 computer and reflash it to the 6.0 program with a new harness?

Personal opinion from what Ive read is to do the 411 swap and it allows you to do just about anything from there.

Go with Nelson harness and tune with the 411 comp, use a cable throttle body/ intake setup, keeps things super simple!!

Man just take the PCM out of the Donor truck/car with harness do the drive by wire and send them the whole wire harness and everything. its pretty easy from there mine is a 96 i drive mine every where i drive it on long trips and every thing and beat on it when i have the opportunity.
