do i need to have a remap and and get a new fual pump if i want to upgrade my injetors from 330 cc to 440cc thanks

 

yes to the remap, your car wont run properly and you wont get the proper gains without a remap. As for the pump it is not essential but would be worth doing, IMO you're better off getting a few parts like injectors, pump, turbo etc to go on, then getting them all on and then having a remap ... saves money in the long run.

As far as I know just adding bigger injectors wont give you more power but may have a negative effect on your engine without being it being tuned properly for the new parts (ie map)
