Meaning a shop that's taking into account the headers and whatever exhaust setup I end up with?

Cause I'm wondering what the worst case scenario is if I got the stock tune flashed back. I recall my mechanic warning there could be engine timing things affected or other such things and cause a bit of chaos. I guess the point of doing a third-party tune would be to make sure they're tuning for the car's current state properly, and not its typically stock form?
