Poor choice making the eBay purchase -- Sounds like you either got screwed with a fake/broken JB+ or when you're putting the tune on, it's inducing misfires since you're running the car at a higher performance settings. I'm dealing with this right now -- My car was running at COBB Stg 1, but now that I've bumped the tune up to Stg 2 the car is misfiring (replacing the plugs/coils this weekend).
