Injector pulse width 0? log inside

Hey guys,
I've been having some sputtering issues in 3rd+ gear after a long winter swap (build below). 1st and 2nd in boost are ok, sputters a tiny bit at constant speed (cruising at 15, 25, speed limit stuff). An example is in the log, logID 120-~300 is all constant speed (school zone) and every couple seconds i would feel a slight bog.

Maybe you can tell by the waviness of the O2 sensor readings? they swing from less than 0.0X to 0.7+ pretty quickly. everything else in the log looks pretty normal. below is a graph of what my O2 is reading during the constant speed cruising. O2 sensor is brand new as of today, logs from the previous sensor look the same.



Looking through the logs, I see that IPW drops to 0, most of the time right after a sudden change to TPS %, but not all the time. I was under the assumption that it should go to the min IPW, not 0?

Sry for English. When you decel(brake the engine), in 1 second the fuel cut takes place. And resume when rpm < ~1200
