do you have a gauge? if you do, set it at around 41ish... drive it around and see what it feels like.

Yes I have a fuel gauge installed in the fuel rail! I'll start with 41 and see, how will I know to increase or decrease the pressure?

make sure to disconnect and plug the vacume line when setting the pressure, then re-attach when your done. Also an air/fuel guage works great and they're not hard to install.
