Looking for 600hp at the wheels

I dynoed 9/18/10 at 553/1025 with 80hp tips an smarty catcher software an dr.p stage3 on stock turbo
 
What's the highest HP with a 66mm turbo and no nitrous or water/meth just good ole #2?
 
Hey sorry man I would love to have them but I just bought a livestock trailer and am starting into the trucking business so my hot rod project has been put off for a while. Thanks anyway
 
with a smarty, 120s, 62/71, LBZ cp3, 5 inch exhaust, and a fuel system I made 552 at TS in 09 on dunbars rollers. I then dynoed at Scheid this year with the 68/83 and made 579. I dynoed it again in Sep at the jamboree in Indy on a different dyno (dont remember the brand I have the sheet) I made 589 with a ED 68/83 with the truck in my sig 03 HO with 154k on it now. Im still trying to make 600 so Id like to hear suggestions on what Im doing wrong when I hear people making more power with smaller chargers.
