What is a good fuel pressure for a obd1 gsr with I/H/E, intake manifold, skunk2 ecu program, and aem fpr? I am currently at 41psi at idle, when full open throttle it's at 44-45, once again thats only when at full throttle it goes to that.

 

Assuming nothing else is changed, you need to know your air fuel ratio at the current setting, then change it if you need to. Without a wide-band it's just guesswork, I'm guilty of it too, I'm too lazy and cheap to go to the dyno every time I play, currently I'm experimenting with lower fuel pressures, and higher VAFC settings, I'll let you know how it turns out.
