My observations are subjective and I can't see what the IAM is doing, but after a hard drive (ex. autox) the car is noticeably quicker for the next few driving cycles, even driving to work the next day. I always assumed this was because the IAM had ramped up with learning with the high engine loads and rpms, and would then back off to a lower number with daily driving. This is quite consistent and within a couple of days of daily driving it is back to feeling "normal". This is with 94oct gas.
