So I've had my emissions fixed awhile ago. The truck now has the head go bad, but it's not because the delete. Truck has 900,000, so it's about time. Since I need a new head and cam, I'm doing a full inframe also.
Here's my question. Mack is saying that having the dpf deleted is fine, but I should have the ecm programmed to keep the EGR functional. Reason being is that it helps with cooling. (EGR is currently capped off). Does this sound right?
I thought with the EGR working it would send hot exhaust gas back into the motor and it would be less efficient, but the Mack mechanic is saying it's just the opposite.

Can anyone shed some light on this?
