I am going to get her put on the rollers and tuned by a reputable tuner. Dyno tunes here in NY start at 500$ So it will probably be a month or two.Why go all that way just to skimp out in the end? That's like working to get a girl butt ass naked, and then being satisfied and saying, "Thanks! You can put your clothes back on now!"
If the tune is from Vortech and the car was bone stock with a S/C then I personally would trust it. Even with other mods I would feel safe with it. Vortech is a large name with many years of experience and trust. They don't just go around blowing up engines. Their tune might not squeeze out every single last bit of power, but I'd bet my shorts that the engine will be safe. I mean, in all my years in this hobby I have never ever hear one person say that their engine blew up using a Vortech supplied tune. I've never even seen one thread complaining about this.
I'll agree, however, I've never read of any of those people driving the car "hard," as the OP intends to do. Normal driving around, especially until the car can get tuned, then ya I've read of that. But beating on it, no.
