Can I delete EGR only?

[Nyc Dito]

Hi all. i've been lurking for a few weeks and I just picked up a 2013 35d and have done all maintenance and logged about 3k miles so far (Road trip after 1 week ownership). Also had a Stage 1 tune done by my indy while I had the car there.

Anyway, I do plan to do the complete DPF/SCR delete later on with the Buzzken kit, but I was wondering if I can do JUST the EGR throttle delete for time being. My indy will be doing the valve cover soon along with some preventative maintenance and I figured since they will already be in that area, why not?

Online searching usually just shows the entire delete being done, not just the EGR throttle. Any downsides?

All opinions welcomed, thank you.
