You can try them, the function works. As far as being easier to tune... might be a longshot.. the stock injectors should be the easiest to tune.
My proposal to you is to put in a boost activated voltage clamp. As soon as it sees "X" psi clamp the voltage enough to where the ECU believes it is in OPEN Loop, this may make your tuning easier.
