Any driveability quirks at part throttle?

This is why I tuned the MAF table ,
there is still some spikes in the table that I need to fine tune.
I had to remove the oversize TB because I did not had time to connect the hose coolant and bleed the system. It was only to look at the power gain in general.
one thing for sure is the Idle screw need to be adjusted ! I was running 1200-1300rpm Idle.
other than that everything is running fine.
