Default 95 LT! 383 w/hotcam which FPR to use?

I also upgraded to 32 lb injectors. Will the OEM Fuel pressure regulator be ok for this upgrade? Or do I need to go with an adjustable FPR? What fuel pressure should I be looking for? Thanks guys.

What is the rated fuel pressure for your new injectors? if 43.5 no need for the Adj FPR. The PCM is going to need a tune for the 383 & 32lbs injectors.

The tag that was attached to the injectors says 32lbs @43.5 psi. So, looks like I can use an OEM FPR. Thanks for the reply.

You are right and when my PCM is sent out for reprograming, many other things will be set up correctly. Thanks for the reply.
