Also...stay away from the handheld powertuners and such...they don't have the capabilities that you will need to make this kind of swap work....like turn off VAT's (some will), change firing order bank assignments, etc.

HPtuners or EFI Live (more $$) are the only ones with the capabilities we need.

But I can also use the HPtuners to tune/diagnose problems on my 6.0 Suburban too...

Or you could look for a used HPtuners...to save any more money....just make sure there are credits left on it...or that it's really cheap. make sure it's the newest version though...
