I always, after every mod folks recommend to reset the ECU. One method is to disconnect the negative battery terminal for a half-hour, or locate the ECU fuse and remove it for a duration (prob half-hour). I usually do the battery, but the drawback is:
1. You lose your radio presets
2. If you have an adaptive automatic transmission, sometimes it has to relearn your driving style.
ECU Fuse: Drawback: finding the right one and pulling it.
