Default Why does it studder when shifting at low RPM?

I am going back and fourth with my tuner and this is the 5th tune he has sent back to me. We got the AFR dialed in and the car rips at WOT now. Problem is, when just cruising around, it has a studder when getting back into the gas when switching gears. Its like everything is delayed when getting back into the gas or something. He keeps doing different stuff, all of which doesnt have much good effect on this problem. If I get the rpms up to say 3500-3700 and then switch gears and get back on the gas pretty fast, the studder seams to not be there very much. Does anyone see anything obviously wrong with this log/tune that could cause this? I don't know much about this tuning stuff yet. Car is a 99 camaro with cam and D1 procharger and M6 obviously.
