What else do i need to do?
So you plan on HC next year and replacing the injectors again? why not just go big now? unless you already have 42lbers on there
Also I have read numerous times that its better to go with bigger injectors 1st, i'm not sure how injectors work but I assume that 42 and 60lb injectors work in a similar fashion under normal loads, but the 60lbers have the ability to handle the big power that 42lbers can't.....
I'm sure more people will chime in with their opinion, but it seems the general consensus is that 8psi is safe with a good tune, and its better to go with bigger injectors.
BTW I would forge the motor if I were you so you can run higher psi
