Tell your tuner to extend the pull past peak power down the "down slope". That's info that we want when trying to figure out shift points. But looking at the curve and extrapolating from that, I would say that you are shifting too late. You may make 7300 on the 1 to 2 but you should be lower on the 2 to 3. You aren't getting to 4th correct? Do you have any pulls that show your 7k to 7.4k area?
