Can my setup handle a 3.6 pulley?

I have a 2011 grand sport with an a&a supercharger kit v3-ti with a 3.8 pulley, stock lower pulley, 80lb injectors, kenne bell BAP, snow performance methanol injection, American racing high flow catted long tube headers, corsa sport x pipe cat back. It put down about 590 to the wheel on a dyno jet making 7-8 psi of boost. I bought the car like that but I’m looking to make mid 600s power. The car drives great and smooth as is. If I downsize to a 3.6 pulley aiming to make a few more psi, will the current setup handle it reliably? I plan on going catless as well before I send it to the shop for a tune. I just want to maintain reliability and drivability while getting some more solid power. It’s practically my daily in the summer time on the east coast. Plan on getting it done at east coast supercharging.
