Another question for the experts

I know it is not recommended to drive the 6.7l at lower speeds and light loads. However that's not always possible. This question would apply for both auto and manual transmission trucks.

While driving in a low speed, low load situation, ie: city traffic, winding roads, etc... would it be better to downshift and run the engine at a higher rpm? Say 2000-2400rpm. This in my opinion would keep the engine from lugging and therefore producing as much soot. Plus it has the added benefit of better braking from the engine brake. Am I full of soot on this hypothesis due to the egr or is it a sound practice to continue doing?

I'm just trying to get some ideas on how to prevent potential problems without having to delete the egr and dpf, though that may come at some time in the future. Especially if I start to have issues.

Thanks for any ideas and opinions.

Duane
