If we upgrade to Si trim + already have the 9psi pulley on and want more boost, which should we be getting?

I'm going E85 route so wanna crank it up a bit, happy to go around 15 psi
Doing the serp side pulleys will give you a bit more boost. Other than that, the only way you can get more boost is by going with a smaller sc pulley and overspinning the blower or removing your air filter. You won't get near 15psi though. I'd also keep in mind that boost works differently in a sc setup than a turbo.
