missing with the throttle barely off the idle stop...at all RPM's..

Adaptive systems only TRIM out cell values. They will not and can not run a cell value to an indefinite extreme. If the available trim "window" for a cell happens to be pegged, (say plus or minus 15%) it's up to you (or dyno tech) to shift the base value of the cell window. Adaptive systems also don't adjust spark advance curves, or acceleration enrichment values. That is up to you.
