he has no significant misfire

also it has same behaviour both while using PI or DI
with DI ltft is even higher since the tendency of the stock injectors to lean out a bit because they are unbalanced in respect of the DI
to me the suggestion of Edelbrock is a bit of a waste of time, but since you can... do it
I took a look at all of his logs, the trims and all the other values (afr, injectors opening time and fuel quantity) look ok
Ltft goes high with maf voltage under 1.3volts, but to me, it's high because it really needs that extra fuel caused by a wrong maf scaling down there

The car even idles not bad, when i had a intake vacuum my idle would rise by itself and swing a lot and throw huge quantity of fuel that immediately be seen from logs and an extreme smell and ample from exhaust
Maybe i'm wrong and it's mechanic, hope you resolve
