using 90 mm throttle body creates rev hang

Hi, I use a 90mm throttle body on a 2.0L K20a (250whp SAE) on dynojet

the engine when upshifting in part throttle is doing rev hang.

Does you have an idea if something could be done to reduce it? since the throtle plate is big

thanks

If you block the idle valve, does the engine stall? If not, the throttle plate is leaky. If it does, then the idle valve is gummed up.
The throttle is mechanical. It can't be the ECU control.
