Fine tuning Mypin PID T-Series

[northdakotaoutfitting.com]

I have the auto tune set up but it over shoots just a little. I have my target temp at 99.5 and it stays at 100.1-100.2. Any idea how to further adjust this pid to get it closer other than lower my target temp? Maybe that’s what I should do but I was pretty sure there’s a setting I can adjust. Here’s a few pics of my set up. Have a few more things to do to it yet.

I would double check temps with a reliable manual thermometer at egg level. Then compare to electronic readings. Nice setup.
