I was told it should be arounf 40-42 psi, but that was with stock injectors. Being you have bigger injectors your fuel preasure will not need to be as high. I do not know forsure what it should be set at, but you can use use your Air/ fuel gauge for now to get an idea if you are lean or not. The chances are you are rich at 25 psi with those injectors. I would call a shop or the shop you got the injectors from that know a little about that and ask, if you do not get an answer you feel comfertable with here on the board. Let us know what you find out.
