So my buddy has a 05 duramax and his stock injectors are going out and wants to upgrade . All he as done to is truck is a chip, its a daily driver and he pulls a horse tralier every now and then. Any help would be apprecaited.

 

stick with stock injectors they can give him more fuel then his stock charger can handle so there is no need for larger ones.

I would stick with stock injectors

 

X3 the stock injectors will over fuel the stock turbocharger, there is no need for bigger sticks unless he plans to make 600hp or more
