4bar map sensor issue

I had just installed the 4 bar map sensor on my k20 engine. Its automatic transmission. I've used flashpro and select the 4 bar map sensor function and flash it into my car. Now I am getting high RPM in between gear shifts.
Example, wot, red line is at 6800, and rpm will drop to about 4000+ rpm after shifting to the next gear. But now, it will overshoot to about 7300rpm. I have to use paddle shift and drive like manual; where, everytime i change gear, i have to let go throttle for 1 seconds.

Which parameter can i adjust on the flashpro manager ?

What vehicle / ECU / FlashPro do you have (as per the posting guidelines).

With automatics the MAP sensor is shared between the ECU & TCU.

Honda/Acura automatic transmission doesn't like a lot of power, now you melted pistons next time you will brake gearbox....
