Im replacing my stock injectors with some RC440cc's and i just gonna drive this thing to get it tuned.

I know there are the 2 boxes under the Fuel trim tab saying Stock injectors and current Injectors. I know in the current box I'm going to type in 440 and hit update. Is there anything beyond that i need to change to get it to run? Mainly I'm concerned with whether or not I'm going to have to use the Calc. button in the fuel trim box to adjust the overall fuel trim or if its done automatically when I input 440 into the current injector size box.

Thanks for the help in advance

I would like to know this as well. any advice? Thanks guys

Changing the new injector size box alters the injector duration everywhere - main trim, cranking, throttle tip in. That shoudl be all you need to do.

Do you have to have it retuned after you put in bigger injectors then?

yes
