Yes our 325 ecu software is equipped with programming that controls the valves. They open and close normally yet the software is programmed for the 325 manifold and the amount of air that used to come in, hence the tune to adjust the combustion ratios.

Correct, there may be flat spots, but the tune fixes this.

Follow the link above.
More like the whole powerband suffers
Finally a solution.
