In my opinion the tuner should always have full control of the fuel map and timing .

But on the new cars from the factory the oem computer controls everthing . If its oem the the computer can control the car down track and its more consistenbut not faster . NHRA has allowed both , but if its a aftermarket computer the computer is not allowed to make changes going down the track unless the car came with a computer that did .

I like were I have full control of the car bracket mode or heads up . I vote open loop
