Default duty cycle can it be converted to e85 from 91?

hi guys.
98 ws6 5.3 t76 turbo 13psi 60# injectors 91oct

my current set up is limited to 550trq due to clutch and would like to hit that
I think my 60# injectors can make it up to that point and very well be max out or close to it.

but im unsure of my current power at the moment. and not sure how far i am.
(in comparison i raced a stock 07 gt500 and walked away slowly(3/3) so i think im around 450rwhp ish?)

at the current pressure im at 80% IDC
is the conversion straight forward? like multiple by 1.3 since it requires 30% more fuel?
in which case just switching would put me at 104% (would not be of any use.)

or not?


what im looking to gain is take advantage of e85 cooling and knock deterant.
aswell as raised the boost more and get to 550whp.
that and e85 doesnt leave me smelling like gas when i drive the car.

im thinking around 17-18psi will get me there?


and yes i know 80# would be a better fit but considering that my clutch is a limiting factor im thinking 80# would be an upgrade later when i change out the clutch and build the engine(its 100% stock 5.3)
if the 60# deka can handle it im ok with it near max or?
