My FD stock only had the 3k rpm hesitation if I gave it too much gas before it warmed up (didnt think it ever had it till that moment of bad judgement.)
Its probably some double throttle/warmup mapping in the stock ecu that cars get stuck in due to mechanical fault (double throttle, thermostat, upgrade radiator) and/or coolant temp sensor drift.

i didn't really nail this down so i didn't post about it, but i was playing with the TPS on mine and i could get the hesitation to go away or get really bad.

I recall looking at one of those patch harnesses some years ago (for a lost less money...) IIRC there is a difference with the later ECM that affects the electrical load detector so idle speed isn't bumped up that could cause a problem. Can't recall exactly though, might work great.
