Those #s can be reached with a cam, pulleys and an E85 sensor using just a 50/50 blend with 93 on the factory pump with a BAP.
I would like to have the parts you chose to put on your car. They are wisely chosen to make good numbers without issues like belt slip or wasted $. I like the idea of 50 50 e85 to avoid the cost of new pump too.
I will have to go back and see what info you posted as per your injectors and cam choice, and any dyno or times info as I might like to replicate your build.
Found the info; FIC 850s and BTR stage 3 kit. Nice.

You said you got about 13# of boost with those pullies, I guess that valve closing mod was worth more than I expected.
