Need help tuning built GSR motor. It has JG manifold, fuel rail, fuel regulator, Skunk 2 cams, springs, retainers, Skunk 2 Pro Series Cam Shaft w/cam gears,stock computer.

Motor idles at 1000 RPM and it'll drop down or die out. Will idle at 1000 RPM for about 5 to 10 seconds and either die or go back up to 1000 RPM.

Anyone know what I need to do to fix this. What should the fuel pressure be at?

Thanks for any help I can get.
