You do realize that in closed loop, no matter what, the ecu is trying to seek on a 14.7:1 AF ratio? You know that 14.7:1 under boost melts things? That's why this is a good idea. it would allow you to no longer have to fight with, or even account for, what the stock ECU is doing with the fuel while in partial throttle boost. You'd have the ability to more accurately dial-in your boosted AF ratio because nothing will be monkeying with it.
