Default 92 miata turbo FM boost lag

I recently purchased a 1992 turbo miata. ECU is managed by a small electical device. The car was boosting steady 200 hp @ 15psi. After installing a stereo system, I notice the car was not running right.

The car seems to boost up to 13 psi then back down to 10 and up and down. I thought maybe there could have been an air leak of some sort. But now I think it might be some ECU setting.

What could be causing the boost gauge to not boost steady 15psi?
