help with tuning
can you please look at the datalog and correct me if im wrong, from what i can see its running rich but then under acceleration it leans out, what do i change to fix this??

400 chev with Hydralic roller cam
Lift: .540''/.562''
Duration: 294°/300°
Lobe Separation Angle: 110°
not using timing control other details needed???

First off, you need to get your IAC steps correct first. I wanna see around 15 steps when at idle and operating temp. Yours are dropping to 0. That is no good.
Have you done a plug read? Send a pic of plug.
How long has this been installed?
when iac drops to 0 is when ive acclerated then no accelation tps at 0 but still high in rpm not at idle , when at idle operating temp iac around 8, pictures of spark plugs 3 clean on both sides but 1 on each side fouled up

Judging by your plugs. There is a problem with something not Fitech related. Valve adjustment maybe. I would expect some difference in plugs, but these have a large swing lean to rich and color.
