Mid-range AFRs ?
My mid-range is at 13.0-13.5, and my wot is at 10.9. If I lower the fuel pressure with my RRFPR will that make my mid-range more lean? Is that safe?

Do you have the reference line hooked up?

stock ECU. My boost line is from the throttle body to the RRFPR. I am waiting for a brass fitting to plug into the manifold.

You may want to just adjust pressure for WOT without the boost line. Don't hook the boost line up, plug it. Check your AFRs.

[QUOTE=Duke;1645770]Is hole open now??
no
Could there be more boost in the throttle body than the manifold? If I move the boost line from the throttle body to the manifold would that make a difference?
Its a Riva RRFPR should I just disconnect the boost line and cap off both ends? Or put the supplied vent in the RRFPR and cap off the boost line on the throttle body.

Cap both ends. Boost is theoretically the same at either location however vacuum is only present in the manifold.
