96 f250 7.5l engine bog

Truck starts and idles fine always. Ocassionally when you are driving you will want to accelerate up a hill or the like (increase load) and it will not take the load and bog. If you back off the accelerator it will return to that power level. If you floor it it will bog for sometime then all of a sudden it will rip off. changed coil, filter, throttle body, idle solinoid and fuel pressure at 30lb but goes to about 40lb when vacuum drops. Checked egr and it positions great at diff vacumm levels. I dont see where there is a maf on this beast

Re: 96 f250 7.5l engine bog

engine is running lean, cannot find a vacuum leak and but the engine idles at 700rpm. changed egr as it was the only code I got but it tested god so it was sort of a last resort. Fuel delivery system is good. lots of pressure. Changed out MAP and o2 as well, no change plugs are hard white. ECU?
