Still trying to get fueling there

[DaddySS]

I have added a lot to the ve and it still runs with a slight chop, in the 7% throttle 2200 rpm range. It's as though there is an override preventing it from adding enough fuel. Not sure if the strategy should be cracker or follower but I am going to take them 1 at time and try to increase in small increments.

Not sure what else to do...it's getting very aggravating and time consuming.

by chop do you mean lean?

Yes, in all other areas except light throttle, 1900 to 2600 ish RPM it sound choppy - when I go into bidirectional and lower the AFR it clears right up but no mater how much I add to the VE table it doesn't get better.

You mean taking away from VE , adding richen the VE thus increasing the AFR , right ? You say you lower the AFR it clears up ?
In other words if the VE has a larger value it makes the AFR richer ?

Increase VE, which adds fuel and lowers the AFR value ie 12.7 AFR is richer than 14.7 AFR.
