you have a little too much pressure at idle. 20 is ideal. you don't really want under 10 at wot.

I would highly suggest the Airdog 2 165. You can adjust the fuel pressure. Also I have mine set at 19 and I have never seen below 15 at WOT.

I see a steady and constant 17 psi on mine. I can hit 15 psi at WOT.
