Delonghi cafe retro (DCM1385) espresso shot PID'd with pressure gauge

Installed an auber PID unit to help temp stability, then replaced the inaccurate, slow responding temp gauge with a more useful pressure gauge from an Ascaso dream. I'm also using a brass 58mm portafilter from a baby gaggia, which explains the alignment to the left. The portafilter is much heavier and has much better temp stability.
I set the PID temp based on temp readings of the water coming out of the portafilter. The water temp falls 8 degrees F during the shot, so the ideal starting temp of the water at the portafilter should be 205F, with the lowest temp 197F at the end of the shot. 209F seems to be the right temp...

I'm not selling the portafilter, but other 57mm portafilters should work, such as from the ascaso dream.

Hey, I was wondering if you could help me out. I am looking for that portafilter and I would love to buy it off of you
