Acceleration sluggish/no codes
I recently purchased an 09 460. Took it to Atl, ran wonderfully. A few days later all of the sudden it is acting very sluggish. No codes, everything is running beautifully according to scanner. Cleaned MAF sensors and it woke up, but still not 100%. Drove to gym and after gym it is back to being sluggish. Any ideas?

However, this may still apply, and having the latest ECM calibration can only help. For context, my 3ish year-old LS (at the time) was 5 calibrations out-of-date, and in my case, the software update was like a miracle. Again, not sure this is your issue, but sharing in case it helps.
And congratulations on the car, btw!
