8.1 HP/Torque reduction in 2004

[boomer 33]

Anyone know why my 2004 8.1 has lower advertised HP/Torque than the 2003 models had?

same here. I think it was emission laws or the fact that they have a new fuel pump setup. Possibly same HP as before just lower "advertised" numbers.

 

 

 

I want to know why they changed the timmings in my allison . My o2 had better timmings when towing.
