Ford Ranger XLT 3.2L 4x4 2015 Diesel Automatic

Live data from both vehicles,

One on The left side is driving completely normal, the one on the right, has a loss of power, hesitation and black smoke coming out the back.

As you can see, the fuel level input is significantly higher on the poor performing car (Right side)

There was speculation to a boost leak due to a gasket being missing around the EGR valve area, Would this cause this ?

Any thoughts or ideas ?enter image description here

  • Easy enough, fix the leak, then see if it changes the fuel stats. – Moab Feb 23 '20 at 15:41
  • It was speculation to a leak, not a confirmed one. Would these figures suggest there would be a leak ? – Mitchell Feb 23 '20 at 16:27
  • Would possible, leaky fuel injectors give these readings? – Mitchell Feb 23 '20 at 16:27
  • anything is possible but I doubt it is the cause. – Moab Feb 23 '20 at 16:40
  • Would you think this leans more towards a boost leak then leaky injectors? MAFS sensor overcompensating for lack of air by injecting more fuel ? – Mitchell Feb 23 '20 at 16:49
