These numbers don't tell much unless you can add the boost figures also. It does a bit lean at 2800 as you said if you are indeed boosting at that RPMS.
It does also look quite rich at the top end... if you could lean that out you will gain some power up top.
How many psi are you seeing at 2500/2800 rpm?
Overall it doesn't look bad. You have enough fuel obviously. Some fine tuning would help. Why don't you try getting a SAFC or a greddy emange? You should be fine if you build a full exhaust.
