VP V8 way too rich when getting back on the throttle.

Example. If I’m coming around a corner and I give the car approximately 25% throttle, the AFR goes to between 10.0-11.0 and then leans out to a reasonable value.

Which AE table is it and what values should I attempt?

not a tps problem?
or possibly a fuel reg/pressure problem?

I'd say it would be your acceleration enrichment table.

Make small incremental changes by reducing the number in the AE decay (I think it's called) table and see if that helps.

I had the same issue, a blip of the throttle even in neutral would drop it down to around 10.5 then shoot back up to normal.
