I'm hoping it is more closer to the 270-280rwhp range. Having owned a 99 Z28, (dynoed 280rwhp in a auto, rated 300hp), a 01 WS6 Trans Am (dynoed 305rwhp, manual) and a manual vette. The LS3 is rated 403 and has been putting out in the 380s for rwhp. Seems like the numbers on the stock tune are coming in a little lower when compared to other GM offerings.

I can always hope right?
