As long as it's not for an extended period of time, or done frequently, you'll be fine. I'd stick to doing it at the track only, and that's if you're shooting for your fastest time. If you're bracket racing the car every weekend or you drive aggressively, maybe go with a tune that uses the stock rev limiter. There's really no other reason to run it up that high. I doubt you'll see significant performance gains out of 200-300 rpms anyways.
