Don't dump it, at least not yet. Assuming that's a 5 gal batch, that's less than 7% of the whole thing, and a black IPA is going to have a ton of stuff to cover up any off flavor you might get. Give it as long as you normally do and taste it, if it tastes bad then you can dump it out, but I'd wager that it tastes just fine and its nothing but a good story. And don't worry about the starsan, it breaks down into yeast food and really isn't bad for you assuming you diluted it properly. There's even a video out there of the 5star guy drinking some of the diluted starsan straight, so at the levels you've got you'll be more than fine.
