BMS Stage 1 on leased 2018 M3

I had the BMS Stage 1 on my 2011 550i and had a disgruntled employee at my local BMW shop not vandalized the car,I would still have it.

Anyway,I have a 2018 M3 and got my hands on the BMS Stage 1 for the S55. Before I put it in, wanted to hear some experiences from others on if it threw codes when you installed it, any indicators in the SW that prompted the BMW service folks to give you a hard time? Overall happiness with it?
The Stage 1 in my 550 was a blast and never thew a code or discovered by my dealer (in the SW) the entire time I had it. I took it out before it would go into service a put it back in when I brought it home.

Appreciate any feedback you can provide.
