Everything is connected correctly (i.e., not plugged to O2 plugs or anything like that).
Any help appreciated.

Did you never feel the increased power? Or did you have it and now you don’t? As you said, I’d do the uninstall/reinstall first. If that doesn’t help, you may have damage in the wiring harness.
On my previous M5, after having the RaceChip for a while, I uninstalled and reinstalled because of service at my dealer. Either during the uninstall or the reinstall, I pulled out one of the wires inside the harness. I did not know what was wrong, I just didn’t have the power I had before. I contacted RaceChip, they sent me a shipping label and off to Germany it went. After about a week and a half, they contacted me to tell me that the RC was fine, but that the wiring harness was damaged. They shipped back my RaceChip with a new wiring harness, and it worked flawlessly. Still using the same module on my new M5 after Ben @
r33_RGSport reprogrammed it for me remotely. Still functioning bulletproof.
