definitely upgrade the regulator and the fuel pump. Just because others have used the stock unit doesn't mean you "should". When running boost, you need a pump that is boost-referenced, meaning it increases the flow of fuel when there is enough vacuum created in the system by the supercharger. Also upgrading the regulator is recommended. Give the guys at Aeromotive a call and tell them what you are using / upgrading, and see what they recommend.
