at what point should i upgrade my fuel pump and fuel injectors?

 

You won't outflow the stock pump on the stock turbo, and you can't really upgrade injectors on the LNF, no company makes aftermarket injectors for it. ZZP offers an added 5th injector but that's it.

 

so you sayin after i swap out my turbo, i need to upgrade the pump? i plan on swappin to a s256et turbo once i save up the money.

 

Nope, he is saying there ar no upgrades for LNF injectors or pump. I have heard of people having a diesel shop port their injectors and pump to get more flow but I'm not sure that has much of a performance effect anyways. your only 2 options are the ZZP 5th injector (in the intake manifold) or the set of cams with the upgraded fuel pump lobe
