You will need a tune right away. You will run way way rich if you don't get tuned for them when they are installed.

Your tuner should just need to make some adjustments to the injector settings to get you going.

Yeah, you definetly need a tune you could wash the cylinders and lose your compression if the new injectors run at hte same duty cycle as the small ones..

Well if you were going lean with smaller injectors they would add performance, but mostly its just to provide fuel to support mods.

Do you have future plans that will need the injectors? If not, i am fairly sure that your stock injectors will support that cam no problem
