Is there a true plug-n-play setup for a 5.7 with FI yet?

I'm very interested in this. So can I buy a $599 pre-tuned PCM from y'all, use a junkyard harness, TB, sensors, etc (already have), and just plug it up and go? Or?

Thanks,
Wade

Correct but the junk yard harness may need to be tweaked depending on make and model that is comes from.
