I have a Lelit flow profiling kit #1000185. Original owner. I had it installed on my Lelit Mara for a couple of days, but decided that profiling was not for me.
Everything is like new in box. This is the kit without the paddle, but I am including a couple of knobs that will work with it. I never installed the lower pre-infusion spring that comes with the kit.
I am also including a brew pressure gauge for the E-61 grouphead, with a new teflon gasket.
Kit - $179 (1st-Line)
Gauge - $40 (1st-Line)

$130 OBO Shipped Priority Mail.

Thanks...
