Hey I am finishing my turbo kit on my 04 ecotec and am going to get 44# injectors and HPT. Do i need to change the FPR? I was trying to think of a reason of why i would need to since i can adjust fuel curves with HPT and couldnt find a reason to change it to a AFPR. Thanks for your help

My Sig Was To Big

if you can change injector constants, then there is no reason to lower fuel pressure, you can control it all with the PCM. (hpt)


see the sticky at the top of the forum.
