I agree with steveo. The VE table has some issues. Your fueling is dropping sharply after 3k rpm. You may be overcoming the VE with PE and that is why it pulls after you get over the hump. How are you adjusting your VE? The datalog you sent is short with little steady driving. See this thread for how to use BLM data to adjust your VE tables:
http://www.gearhead-efi.com/Fuel-Inj...-data-Tutorial! It also describes how to populate your history table with good data so you can adjust the VE table. It is a basic tutorial based on the $0D mask but the same principles apply for all masks.
Attached is a screenshot of the sample count on the extended table with NBO2 data.
