2002 2.5 200 efi problems getting on plain

[hybridbuster]

All of a sudden my engine on a 200 Superpro ProCraft doesn't want to come out of the hole. Also lost 500 rpm on top end. My mechanic found pieces of gas line liner in fuel pump. New gas line and bulb replaced. Fuel pump cleaned and new kit installed. Injectors spraying good. Fuel filter changed. Firing fine on all cylinders. New plugs. Compression 115 on all cylinders. Engine turning 5400 rpm in test pool with test prop. Back to the lake and the same problem, doesn't want to come out of the hole and will only turn 5000 rpm. Does not skip or sputter at any rpm. Runs fine and idles fine. Just loss of power. Just trying to help my mechanic out. Any help appreciated.

Check fuel pump pressure at the fitting port while WOT

Do another pre-flight inspection of your new fuel lines, pay particular attention to the tightness of any bends below deck and the tightness of any zip ties holding the line to the cables/wiring/battery cables. ANY RESTRICTION in your fuel supply hose can and will reduce WOT RPM and could cause the motor to go lean and toast a cylinder.
