Default Help with misfires

So my car was running terrible, bogging, sputtering,and missing as soon as I got on it. I couldn't even rev freely. Then it would clean up when boost came on. I noticed it was running very lean on low boost/hard throttle. I had a feeling it was the utec's fueling crossover, because the car ran fine at all other times. I also pulled misfire codes on all 4 cylinders. So I messed the the OL crossover, and cleared the ECU. The car runs MUCH smoother now, however I got misfires today on boost/upper rpm's, whereas before it was down low. I was wondering if anyone has any ideas to what this could be besides my utec being crapped out.
