You need a tuner or itll throw codes. Get EGR block-off plates to do it the right way!
Unplugging the EGR wont really help the dpf filter. Recirculating the exhaust gas does increase particulate but not all that significantly. You should do a dpf delete before messing with the EGR or you'll start clogging you NOx filter.
Unplugging the EGR will stop the exhaust gas recirculation into the intake and the truck will run stronger and cleaner (you'll notice a big difference when you change your oil)
