what's the best way to get more than 9psi out of the kit?

The Si impeller swap from Vortech is under $400. It gives you an extra 100 cfm. In my case it was a 3-4 psi increase.

I had the Si impeller upgrade done by Vortech as well ... had 30,000 miles on the SC'r and it needed to be rebuilt once they evaluated it.

Cost skyrocketed past the $1,000 mark.

It did make 11.9 lbs of boost with the 9 lb. pulley

On mine I was seeing 12 also, Stock 8 PSI pulley tho, An my boost was building way sooner right around 3k all the way to redline.
