Still had it. It is the most frustrating thing ever. I never had this issue with Vince's tune. Vince tuned my car twice and it was perfect. That's what I expect and the dang guy freaking delivered.

Spooler, Did you ever get your stumble at 2800 rolling into throttle fixed? I have a 2017 370Z with Fast Intentions Stage 2 with UpRev dyno tune and have what sounds like the same issue you outlined in your post. Thanks for any insight you can share.

I had a couple of problems, but it is hard to say exactly what was causing it. I had a coil pack issue under load at 16psi of boost. I put a brand new set of Nissan coilpacks in the car.
