I can confirm SOTP increase as well on a 2022 M340i.

Racechip is a close second choice for me after the JB4.
I used the Racechip on my G82, and I was pleased with the power/reliability.
Im switching to JB4 this week because I wish to use E85. It's a lengthier install than Race chip but offers more features.
