CM871 Slow Climbing Regen Temps

[Taco05]

When you say engine damage what do you mean specifically? Not enough exhaust pressure, too much blow-by? The pressure we are talking about is the actual pressure drop across the DPF Filter (change in pressure before and after DPF) which should not go about 3 inHg. So if the filter is really clogged and past the point were a forced regen can clean it out would't it show really high numbers like 8-9 or am I missing something? Last regen finished good in about 45min and differential pressure code went inactive, soot load went from least severe to normal but 30 min later it was asking for another regen. I will see the truck today and get all the numbers again including the turbo specs which I am suspecting the most since I have not changed it and it is red which might be the original equipment but the actuator has been replaced.
