How much can the stock blower make with a pulley change and bolt ons and tune, etc?

Without changing out the blower, what is the max RWHP that has been realized with the 2011-2012 GT500?

I believe stock blowers can make 580-ish and ported blowers get you into the low 600s(605-610) at 15psi. Pretty sure I've seen that over the passed couple years of surfing...could be off?

Basic pulley/tune/cai is mid 500s. Add stuff like TB, exhaust, you can get into the 575 range. Porting, lower pulley, or race gas 600. Some have posted crazy numbers from stock blowers by installing cams or dynoing in really good conditions, but I think most people are not going to those lengths.
