Taking off the butterfly ?

I have read some where that taking off the egr and the butterfly helps. But the question is does it and why? I know the egr is not a bad idea to delete. But why the butterfly

The EGR works differently on the NP series, and blocking the EGR will not log a fault code, the butterfly plate is there to provide a quicker shutdown, leave it as is

Thanks mate... i will just block off the egr i have a 2002 nm 3.2 did so it should be all good. I thought it was a strange one to take out the butterfly. Just thought might be good to ask.

I owned a NP for 190000k the EGR was blocked for 180000 of that never a problem

If you remove the butterfly it will throw a code. It is actually designed to force the motor to draw gas from the EGR, as well as closing during shutdown. Been there done that...
