Ecu mapping will need modifying if you are reverting to standard air box from an IK
The standard Ecu relies on the airflow meter for fuelling and engine load calculations -
Airflow scaling is dependant on the size of the tube the maf is sitting in which is unlikely to be the same, and the way the intake air is passing over the sensor element.
At least get it checked, then it can be altered as necessary.
