VATS PWM is not the same PWM that controls yout converter lock up. You can not turn lockup PWM off with HP Tuners. It is something that is converted from PWM to on/off with a modification to the transmission. If you have a built transmission that is vacuum modulated, there is a good chance your transmission builder already converted the lockup PWM to on/off. Check with yout tranny builder.
