Help!!! :( Pulley Sizes & Belt dont match!

The fact your running low octane fuel is going to hurt. It will be hard to keep knock down. You can only compensate timing so much when you throw boost at it. Good fuel is a must for good power. I'm guessing by not having your blower spin any faster is a good thing untill you can get some better fuel into the build.

Yeap. I totally understand that it will be not as powerful as it can be with running 91 octane.
However I am just concerned about safety and very nice driveability first as it is my DD.
My tuner and I both understand that e85 will definitely bring more power to the car overall, but we will do 91 octane first and then slowly transition to e85 once I get the CJM S1-SE return system which won't be for a good while and that's fine with me.

And yup, you're right haha, By not having it spin any faster is a good thing so I think the 3.0" SC pulley is a good fit right now Will lower the size later!
