Every dyno is different. Different conditions yield different numbers. Who knows how many runs Kenne Bell had to make to ultimately produce 517 horsepower?
Adam at ST Motorsports knows his stuff. If he's confident in the tune in terms of engine longevity and, most-importantly, the customer is happy, then that's all that should matter, really.
