If don't have anything controlling the injectors, you'll need at least an 8:1 FMU.

you will need something controlling your fuel. I am using the same set up and also using the 12:1 fmu

a little bit, but its perfect. I was running just the 255 and the fmu before, got it dynoes, then putt he 310's on and it jumped up 20 whp and like 15 torque.
