Default Will I need bigger injectors with these mods?

well as of now i got
tbe
cai
walbro 255
crank pulley
fmic

going to be installing soon
PnP exhaust and intake mainfold PnP tgv's and throttle body
also going with a turbo xs ewg kit 44mm
btw i got a set of PE 850's but i wanted to know if i need them or not.
Its kinda a hassle to put them on then tow the car 40 mins away on a flatbed to get re-tuned

so my question is will i need bigger injectors or will i be ok?
or if I do put bigger injectors on this setup will i net bigger gains?
also would i need another tune just running the PnP stuff with the ewg setup?

the PnP would be ok to drive but I don't know about the ewg, I have little experience with that. I would be skeptical to drive with an untuned ewg setup but I can be very wrong.

The 850's would work but not necessary. They would be going overboard for the VF39. Unless you have plans in the near future to upgrade turbos, then swapping them now will save you from it later.

I hope you have a tune for the cai and fmic

Good luck with everything
