Why is there a deep hole ?? Maybe one or two cells in the fuel map . Lower left hand side of the map . Is this what the engine wants ?? Terry ✌️

This is an aspect of the fuel system in the Subaru STi. It creates high frequency oscillations in the fuel pressure which affects the actual fuel delivered by the injectors. You could consider this a work around to get the right fuel into the engine.
