Is your transmission vaccum modulated? If not it needs to be...And also, some cars dont like descreened mafs...A way to test if your ported/descreened maf is the culprit would be to flip the MAF around and watch your shifting get crisper. If it does, its a MAF airflow problem that can be rescaled, again with a competent tuner.

Another thing its not just happening in the idle area...Alot of times its with 01-02 cars with a 230+ or larger duration cam. I want to say the last car I worked with would still do it in gear as I was cruising down the freeway at or around the 15-2000 range. Once i dropped it to a higher gear and cruised it went away. It was definitely tune related though. Once we made some changes in the tables around that MAP Area it was all squared away.
