I see that its a 5.3 liter engine but what transmission do you have? 4L60E? I likely have a tune I could send you to put into your new junk yard PCM but for now, leave your original PCM alone. Always, always leave yourself a good PCM to run the vehicle with - ALWAYS!!! Is this your daily driver vehicle?
What state are you in and does it have strict emissions control laws?

I’m in Georgia. I’m not sure if I’d call it strict, but you do need to pass to get your registration.
