Update 1/13/18: So Jon and I drove around for awhile, while he did live tuning. He could see every single jerk and jump as soon as it happen and he adjusted and smoothed them out section by section of the throttle load.
As you guessed, the Tial BPV is causing some of the jerks, right at the point were it closes/opens under light load, confusing the MAFs. He was able to trick the MAFs in that area though to help the jerking. The issue is about 90% better, SD I would say is the only way to 100% the issue.

In short, if your uprev tuner is good, they should be able to smooth everything out for the most part.
