i bought a vortech fpr and b&m fp gauge from my friend, after i installed it i later find out your supposed to get a baseline fp first then go from the there,its set at 38 psi at idle now. the book says 39-46 at idle, why the "to"? does it vary from gsr to gsr? i just want to set it at stock fp just to ease my mind until i hit a dyno w/ more extensive mods.

 

stock fuel pressure is 40psi with the vacuum line hooked up
