16 tundra mag sc top end fueling problem

stock airbox, cb exhaust only mods besides magnusson s/c. using mag fuel pump and injectors.

on top end always getting this problem where it hammers the engine with fuel. goes off the chart. looking at the log though, you don't see it. i don't know if the log is not reporting correctly or what's happening. and you can see it's not always the same place. i have changed the torque tables, desired air load tables, anything i can think that would do fuel, but nothing stops this.

only thing i see as different from others i've had is this is a flex fuel truck. in the log you'll see showing e78, it's on 91. mpg is garbage too. i know there were problems with how toyota was doing a virtual ff sensor and i'm wondering if this all related somehow.

any help is appreciated.

Im having the same issue, it seems to be no way of disabling the FF option on these computers.
