Nothing stands out to me as a clear cause for jerking.

You would probably be better served by an intercooler upgrade. You IATs climb significantly over a single gear pull. They would be even worse with a multi gear pull. Likely to the extent that the dme would begin to pull performance.

Your timing is a bit rough. Do you have anything that can improve your octane? Higher octane pump? E85?
