Default E85 Flex fuel requirements for my setup

I want to install a flex fuel kit but am curious if I will also need a larger fuel pump and injectors.

My car and mods:

2012 Grand Sport manual
A&A SC V3 Ti trim currently running about 9psi
A&A stage 1.5 blower cam
80lb Bosch injectors
boost a pump
long tubes
high flow cats and x pipe
Exhaust

*also what can I expect for HP gains on a full tank of E85?

Thanks

Yes you will need a larger pump, either new in tank pumps or external, and larger injectors.
i would expect about 50 rwhp gain from e85.

At least 1000cc if not bigger.

At least 800lph of fuel pump.

Assuming you are going to turn it up.
