Fuel Pressure advice/leave it alone?
I've been reading a lot of other posts on this topic and have a question, my 91 Camaro RS with the mods in my signature runs great and pulls hard to any rpm in any gear. I've never adjusted the fuel pressure because the car runs great. I noticed the tab on the stock fuel pressure regulator is near the bottom of the regulator (as it's mounted on the manifold) which would indicate a low stock pressure setting adjustment so my question is, should I just leave the fuel pressure alone. I've read other posts from people with the same mods I have and they say they're running lean but, I don't want to adjust something if I don't need too.

If the car is stock and running well, I'd leave it alone. If you have some way of measuring small improvements(G-tech or track), then you could try bumping it up and checking it.

Always tune fuel pressure! Telling a carb guy to stop waisting his time with changing jets unless he's at the track/g-tech is not recommended by me.
Play with the fuel pressure and see what the car likes, just remember what the stock pressure was set at so you can go back to it if you NEED to (you won't).

Here's a picture of my new Summit Fuel Pressure gauge. This is the stock fuel pressure, since the car runs so well I'm just going to leave it alone.
