I have posted a couple times and an looking to upgrade my V3 sci stock pulley setup. I am looking to move to the 8 rib with the 6.87” crank pulley. What do people recommend for the supercharger pulley size?

After the tune on SCI was only making 5lbs on the stock 3.33” and the 4” power pipe and the bypass.. I would like to get this to 9-10 lb of boost if possible. Should I go 3.12 or 2.95??

Thanks
