Here's what I have now, except the 496 is long gone and I added an EDM-730 with CHT and EGT in the 3-inch hole at the top right above the ELT switch.

The main focus of the refresh is to replace the 2010 Aspen PFD with a new Aspen Pro Max PFD. Their new PFD has internal redundancy that allows me finally to get rid of the vacuum system and keep my IFR certification. So, the clunky vacuum attitude indicator and the suction gage plus all related plumbing and components are gone. I fly mostly in VMC and always in daylight, so I don't feel like adding an electric backup ADI. Plus, I'm cheap.
While I'm at it, I'm also thinking of removing the Garmin CDI that I never use. I'm planning to add some panel-mounted charging ports and (on the advice of my wife) a panel-mounted CO detector like the Guardian 551. And I might add a few probes to the EDM-730.
I'm keeping the Garmin 430W, the SL-30 backup nav/comm, and the Garmin GTX-330 that gets me ADS-B Out. I'd love to upgrade the transponder and ditch the Stratus puck that rides on the glare shield, but that will have to wait.
What am I missing? What should I add while I'm at it? And, I have three specific questions:
1. What power ports do you like, and why?
2. What CO detector do you like, and why?
3. After CHT and EGT, what are the best probes to have on an engine analyzer? I'm thinking MP and FF but am open to suggestions.
Thanks!
