How can I tell if I have egr deleye lmm duramax. I have efi live and dpf delete just not sure if I got egr?????

 

on the engine right near where the heater core hoses enter the fire wall, passenger side of the turbo there is the EGR. it is a metal canister looking tube about a foot long with part of it bolted to the intake and the exhaust.

 

Okay thank you looks like I have it still but just tuned off.
