Default For those that have tuned the L9H 6.2

Are the injector files the same as the LS3/LS7?

I know the L92 just had the 30 lb/hr injectors but when the flex fuel version came out (L9H) I have been told but cannot confirm that they went to the now standardized 42 lb/hr LS3/LS7 injector. I would like to know so that I can find out whether or not I need an injector upgrade when I get my cam (possibly heads too).

Also, do you think these injectors can support 400-420rwhp on E85 and stay at 80% or less?

Thanks, and WOW! Looks like 54 lb/hr @ 58PSI. I may not ever have to change these.
