65 psi?!!? wtf? You know, writing your setup would help. If it's all stock then you should be fine with a stock FPR. Somethings off there, also there's an SR20 forum.

You should have done your HW before going and putting parts like a FPR. Now go read up on how to adjust, it unless someone else post up on here is nice enough to give you the answer. Sure I could tell you, but then you wouldn't learn your lesson.

if you are at 63 psi instead of 43 then you would run rich, not lean.

get your FPR in and turn that bolt on the top to adjust the fuel pressure
