Default 2012 FXDWG 110ci: Swapping in larger injectors and throttle body

bike:
2012 FXDWG
110CI/4" Bore bolt on cylinder and piston kit
S&S 89cc ported heads
.030 mls head gasket
S&S 585ce
I'm getting ready to swap in larger injectors and throttle body(and a/c).

throttle body:
OE 46mm Cable Drive (2P) > SE 58mm Cable Drive (2P), [and matching a/c]

injectors:
27625-06 3.91 g/s > 27797-07 4.9 g/s

i'm updating the tune's injector size (3.91>4.90). is there anything else i need to do in the tune before taking it out for auto tune runs?



i will take it in for a new dyno but, want to do the work myself.

Have to agree with Kirby

isn't this more of a question for the tuning section? There are many who frequent here that are more than capable of answering your question but seems more of a tuning question than a mechanical

To the best of my knowledge yes. ECM needs to know injector size to calculate fuel delivery. I have never seen an option in Win PV for throttle body size, so you don't have to change anything there. Is this the only change from the current tune?
