Can you try to floor it heavily at 2000 rpm instead of give partial throttle?
like 2000 rpm floor it 100%... if you are quick enough it should still cover the zones where it uses 50/50% of injections at least untill 3200 rpm, so the esitation should begin a bit later
in the case it is the DI, don t really know how to help you, maybe some DI injectors is clogged up or faulty
