Bigger injectors to run E85

[maxgee]

I was told going with 79lbs injectors would be difficult to tune, if so why would it be difficult?

I am running 8lbs boost with 42lbs injectors on gas and all is fine, when switched over to E85 and made the necessary changes to the tune (except injectors) I maxed out ... 149% inj duty cycle.

Any help appreciated.

First off, I would not be running the car hard.

Secondly, the bigger the injector, the more fuel it injects at low loads like idle. You may reach a limit to where the car will just not lean out. With E85, it will not be as bad though as it will need more pulse width anyway.
