Pc5 pti question

I have recently installed an osp turbo on my rzr 1k. I’ve got the tune pretty good using the auto tune, the only problem I’m having is a slight stumble when moving the throttle pedal quickly or taking off. When this occurs the afr goes very rich for that split second it’s kind of annoying sometimes. I’ve tried to use the acell pump feature to take fuel out for a split second but doesn’t seem to make a difference. Anything else I can try? Is this normal for dbw machine?
