I have an 03 duramax with 140k and with the truck in the shop needing new injectors not sure what to do. I want to put in 95h injectors but mechanic says I need a high performance cp3. Is that true
I have a faas 150gph lift pump on the truck. So I figure stock cp3 can definitely feed 95s?by going after market injectors can I beat the lb7 injector problems?

 

I would not recommend using extra HP injectors unless you are running serious tuning and a better CP3.

And aftermarket injectors will not last longer than stock ones do.
