i tried searching but couldn't get a decent answer so here goes. i'm getting ready to switch my setup and i'm unsure if i need to swap injectors/fuel pump. i'm currently running the setup in my sig and my tuner never said anything about needing injectors(duty cycle). i'm switching to a set of 243's with a QUALITY vj and some hand blending and a slightly bigger stick. do you guys think the 28.8's and the stock pump will be enough? i haven't found a tuner for the new setup yet or i would ask them. i'd like to have the car completely ready when it gets trailored for the tune. thanks for the help

you should be fine with the stock stuff ,but upgrading is never a bad thing . i'm still using stock injectors and stock intank pump and it seems to do fine for my mild set-up. if you think you are going to be pushing your stock stuff to the limit, then get a set of 30,36,or 42 lbs svo's and a good ol' walbro 225lhp intank-pump . once tuned , you should be good to go.

thanks man. i was thinking about changing the pump for peace of mind. i just don't want to find out when it's getting tuned i need injectors. but if i swap injectors then i can't fire the car to make sure i have no issues from the install. either way it's a chance i guess

Do the install with stock injectors on and fire up the car and look for any issues. Then right before you get it tuned swap to the new injectors.
