I'm sure I could have spec'd as custom cam for my setup, but the GT9 is working great with my D1SC. I especially like the wide LSA for my automatic. Of course, my boost curve is different from other centris because of my wastegate.

For the OP, I added my GT9 before I added the blower, when I was full bolt-ons. I gained 50rwhp. FWIW.
