Lower power after WOT under load
My 2004 F-350 6.0 has low power after full load or close to full load. I. E. Pulling a hill or passing or heavy accel. When it has low power it sounds as if it has no manifold Pressure (Boost). until you put your foot back in it far enough to downshift and wind up above around 2750rpm. Truck...- mikeywrench
