Default backfiring/bogging/shutter - only at 3k rpm at heavy throttle

Hello everybody
I have a 89 7MGTE with an A/T which I swapped last year for a JDM (A341E) with a new Torque Converter:

When I accelerate hard, after 3000 RPM, the car feels like it hangs there for a few seconds (1~2 sec), then it will continue to accelerate.

I don't get any tranny code, and the tranny oil looks and smell right, and I did a tranny flush a couple of hours ago, so i don't think is my tranny. Have any of you guys had this problem before?

any suggestion will be appreciate.

Thanks
