When I first started the mods I had a maggie kit (5.5lbs boost), SLP catback and Roto-fab with a dyno-tune and I was putting down 521rwhp. The internals were stock and the and the fuel pump was stock. On an LS3 with 10 or 11 lbs boost you can achieve the 600hp level but you will need to go with bigger injectors than the Whipple kit comes with and a ZL1 fuel pump or a BAP at minimum.
