if I have a FMU Do I need a AFPR?
 

I have a FMU that came with with my PowerDyne. Do I still need an Adjustable Fuel Pressure Regulator? If I do should I have both running? What brand do you think is the best?
Thanks for the time

What size injectors are you running? If they are stock and the fmu disk is stock I would say you don't really need one. Of course the next mod I would do would be 42lb injectors, MAF, and an afpr. I'm not a fan of FMU's, there slow and sometimes don't react fast enough. Don't be scared of large injectors, the new lightning comes with 42's. This would allow you to grow and you wouldn't have to worry about fuel problems for a while.

Well the Kirban fpr is finnaly on its way. I will be upgrading the stock injectors when I get some heads and swap my stock intake for the cobra sitting right here next to me. My qusetions are should I remove the FMU that came with the blower and what size injectors should I go with? 42s sound dam big can they be too big?
