Did you check the gap on your plugs. I had a hick-up at around 4500 to 5000 and thats what my issue was.

Mines doing the exact same thing.... Except at like 4200. I just changed the fuel filter, and found out my wastegate actuator wasn't connected to the wastegate flange. So I hooked it back up, and now it's doing that.
It's crazy. If you get any break throughs let me know lol I shall do the same.

if i slowly gas it will go with no choke. only when the turbo spool hard is when i get the choke. someone has told me that its my speed box unit but i doubt it. i dont want that to be the problem.
