E85 Injectors enough to hold 550RWHP?

I have a 2011 5.3 that is FLEX FUEL E85 ETHANOL ready. I am planning on doing a MP T70 w/ a .96 a/r Housing, Cam, Heads, Tune & a few other things. My ultimate goal is around 550RWHP more or less.

My question is would the E85 Injectors that my truck comes with be sufficient enough for that power?

Nope. I forget what the E85s flow, but for that amount of power get yourself some 60-80lb/hr ones.

I just got some 75lb. ones for the truck in my sig, going E85 with prob 8-10psi. I was at 95% duty cycle on the stock 33lb FF injectors with 6-7psi on 93 octane and stock exhaust manifolds/y-pipe.
