Renntech EVM install on 2022 SL55
 

Did a quick edit of the EVM install process here:
Will be doing the ECU tune next year!

just bringing this to the top level, it was a response in a thread on exhausts

Thanks for posting! Is the sound noticeably louder compared to when the valves are open in stock form? I would like a little more volume so curious if worth it. . I considered ordering the Renntech exhaust mufflers but I thought I read on here that 1 person had installed them but was getting a check engine light, and the dealer was working with Renntech on it. Now I can't find that thread. Also I really like your spoiler! Who makes that? The carbon matches your color well and would not look as good on my white car but would consider painting it.

Thanks

It's noticeably louder in comfort mode but very subtle in Sport Plus (but still there), it seems the stock valve opening button opens to different % depending on mode and speed so you never get 100% open in comfort but probably get 90% in sport plus.

The wing and mirrors are from Mansory, the whole kit is not my cup of tea but these few parts are quite nice but expensive. I think Brabus has some trims now but this is the only full carbon wing replacement I've seen so far. The wing is bolt on but the mirror caps are glued on so I had my dealer replace the mirror caps with unpainted ones and I glued to that so I still have the body color caps I can put back on if needed (for trade-in or resale)

Yup, this is correct. Example on a different car:
