hey guys, i need to know what I should set me fuel pressure to. I have a 91 gst, with a 2.3stroked 6 bolt. Now I know 1g's are supposed to have 37.5 psi for fuel pressure but thats with the 2.0 not a 2.3. Can anyone tell me what I should be running, thanks a lot

Stock pressure. 37.5psi if it's a manual or 43.5psi if it's an auto. Remember with the vacuum line disconnected.
 
No, you don't need to turn it up at all. The only reason to turn it up is to try to get more out of your injectors.
