Default Initial Startup After Swap

Hello, I I’m in the home stretch on a L33 swapped Sonoma. I’m running a pcm from a 5.3 DBC Silverado.

Once my HPT arrives, for “first step” initial testing and startup, I assume I need to disable VATS??
And, is there anything else I need to do and/or any well known issues holding back a engine/pcm swap?

P.S. it’s milled, ported, cammed, long tubed, and LS6 top end’d... if any of that will effect it just simply “starting” so I can check for leaks and what not before going to a dyno/tuner.

A stock tune won't work very well with those mods. It might start, but it probably won't idle. A good tuner will probably have a "base" tune for those mods. Then, they can fine tune it from there.
