Still.... 690 crank hp would equate to roughly 570 at the wheels. I'm pretty pleased with that on a 100% stock vehicle.

RK Tunes is a US tuning shop in the northeast. Jordan is their tuner. They ran intake, downpipes, and exhaust to get those numbers. This is DI, so no need for fuel system upgrades. I believe virtually all of the power gains are catless downpipes stacked round the tune. Virtually all the tuners believe the stock intake is sufficient with a better filter. Removing the charcoal seems wide as well, but no dyno to offer true insight yet.
