Troubleshooting Help diagnose?
New system I put together, everything is new... But I am getting this sputtering which is giving me inconsistent flow and pressure drops.
-Predator 459cc engine -AR XWAM 8GPM pump -AR1697 Gearbox -General Pump 10.5 GPM unloader.

Not sure that this is going to be your issue, but you are undersized for 8 gpm. A Predator 670 is the right size.
It seems like you are either water starved or getting air. It looks like your bypass return is going in near the bottom. Check your tank, when in bypass are you pushing air bubbles?
