Are you able to do any data logging or monitor your A/F ratio? If so, see if your afr is outta whack. Under hard acceleration it should be around 13 for na. Cruise should be around 15. Again, I wouldn't be concerned about chasing down that small of a difference. Also, it may be smaller than you think if the monitoring/iat sensors are out of calibration by a couple of degrees.
