Here is what I see

Maybe flush out that part of the VE table it appears to be more flat in those areas based on the trend.
Use the wideband gauge for reading wide open throttle numbers because of analog offset. Compare gauge to log to know the true values from the gauge and adjust the log so it matches the gauge.
Make sure you prepare analog offset term in the user maths like this 2007 thread explains otherwise wideband is useless might as well not even have one. I based my offset on your narrowband oxygen sensors but on the assumption you have 0-5v wideband and that that was at a specific RPM and the analog offset will change slightly depending on the RPM and electrical load, so it isn't a set and forget term, you will need to take multiple samples and prepare analog offsets maths for highrpm and lowrpm and sometimes even day/night situations.

2. The larger the injector the better. Shoot for low duty cycles 40% to 55% is nearly ideal. I'll use Haltech firing angle for reference because it is universal and easy to understand. Haltech references in before top dead center compression, so 360* BTDCC is firing an injector 360 degrees before compression TDC, in other words during overlap of intake and exhaust and the worst possible time to spray an injector possible. You prefer either timing in the range of 410*BTDCC which gives fuel a chance to vaporize, this is the factory method of letting fuel pool or smack an intake valve where it boils off into the runner and creates a column of fuel vapor if the valve is hot enough. The factory HPtuners value of 5.55 is probably around there. The second method is a timing between say 300*BTDCC and 215*BTDCC which is during the time when exhaust valve is closed but intake is still open, allowing you to get fuel in during the intake stroke, which may dramatically improve torque (cylinder filling) and engine response in some engines/combo. To do this however requires a large enough fuel injector to fire within quickly that range for those low to midrange torque situations, around 30% duty cycle maximum window. The larger injectors and reduced duty cycle also keeps the injector drivers cooler, the electronics more happy, less current draw keeping injectors open, larger injectors has all positive benefits for modern high impedance quality injectors.
