I could definitely see that happening. The stock ECU is set up for the stock airbox and exhaust. Altering those componets without an ECU reflash, tuned Power Commander etc. can mess things up.
Now you'll probably blow my mind by saying that GSXR had a properly tuned air/fuel controller and still lost power.
