I am running twin computer injected 115's, starboard runs perfect, port had problems at idle but was rectified by full fuel system clean up including filters, have even run from New clean fuel source, by passing all filters direct to engine. Engine will rev to 3000 at approx 1/2 throttle position, any further causes engine to labour and return to limp mode. Re engage throttle, same scenario. Have swapped, one at a time, all easily interchangeable components from good motor to bad, including computer with little or no change. Tps units on each motor tested for resistance (ohm's) with both returning like results (good) . Dr H program, when plugged in shows good results accross the board. Fuel flow and pressure is good. Anyone have any ideas, I'm stumped, injectors ? Any advice greatly appreciated.

Try checking all your fuel filters. There should be three fuel filters. Fuel/water separator on the boat, low pressure filter, and the high pressure filter located on the side of the VST right above the high pressure fuel pump. Did you check the fuel pressure? The fuel pressure should register at 35 psi. Hope this helps....
