Default what size injectors for 6.0 maggie and e85

I have a 2007 6.0 with a mp122 I bought off a member here and I am finally going to install it. I would like to run e85 but need to know which injectors to buy. this is in a 67 chevelle. The engine is all stock but I may stick a cam in it but not right away.

How much boost and/or rwhp are you shooting for?

FIC 96'ers should work pretty good, imo.

I would like to have 550 rwhp but I dont know if I can do it with what I have.Any suggestions are appreciated. There is a 2.9 pulley on the charger right now and I still have to put together the intercooler set up.

I am at about 90% IDC with my 75#'ers with E85 on my 5.3, GT2-3 cam, MP112 with 3.0" pulley (probably about 8-10psi). Call Jon at Fuel Injector Connection, that's where I got mine speced out.

Swap the map for a 2-bar sensor and trash the MAF as well, go with a speed density tune.
