If your installer disconnected the battery during the install, it will take a few minutes for the ECM to relearn. Go for a 15-20 minute drive, under varying load conditions.
Or they may have forgotten to plug something back in. Or broke a connector or sensor. Use an OBD reader to look for out-of-spec readings.
