Somewhere between some and none. Think about your "question". If the well's afterflow is 100 MCF/d at 200 psig, then changing your line size will make zero difference. If the afterflow is 7 MMCF/d then why are you running a plunger?
The only way to get a meaningful answer is to post a meaningful question. It helps to kind of explain the before conditions before asking someone to predict the after conditions.
