Go to your VE table and multiply the 400 to 800 rows by 75% (I usually do the 1200 row about 85% as well). Then go to your base running airflow and multiply those by prolly 150%. That should help you out.

this seems to happen more when the car is warm, at operating temp.

Its running open loop when its cold. When it transitions (warms up) into closed loop you will notice it surging more. Try the above recommendations. Should help you out.
