Question regarding removing my DPF and driving it across town

I'm taking my truck to my buddies muffler shop Friday morning to install my new 5" exhaust but was gonna drive it back to my shop to remove the EGR and update the ECU w/ my Smarty?

Will this do any damage other than throwing a check engine light or code that I will need to clear before I install the ME software?

I thought about that but the Smarty manual gave a severe warning about running the me software on a truck that still has the factory egr set up. Something about back pressure?? or were they referring to the DPF only?
