The stock calibration does not turn the secondary injectors unless it meets the parameters to go to the PE mode, I think it cuts the time to .57 of what is commanded when in single injector mode. You can also use this parameter to increase fuel if your PE table runs out of fuel. I recommended this to Jim Smith for that on Ron Ks car as he was leaning out on the dyno and would not respond to additional fuel increases in the PE table. It worked but he did have to go back to the PE table and pull some fuel out at top end.

My car calibration runs both injectors at all times. Throttle plates are removed. With the code mod you cannot jump back and forth. It does not matter whether you run one or 2 injectors you adjust the calibration in the code to meter whatever fuel is necessary, WOT or idle.
