after talking to shaun (1fast) today about FPR, i was wondering at what point does it need to get upgraded. im using a aeromotive regulator, but didnt want to suggest upgrading if the stock one is fine. how often do stock ones fail? at what point does it not support enough
he is upgrading rails so, nows the time to upgrade,what do you suggest for him

Stock FPR here...

There isnt much need for an adjustable. They make the car harder to tune, and generally the fuel pump can't dish out the pressure the stock regulator demands, let alone a stiffer regulator...

Keep the stocker, and keep headache free. It's much easier to swap injectors.
