Frequency & specs of Boost Control pwm

[speedengineer]

Hello,
I intend to make use of the boost control feature to control a water/meth injection system. I have a couple of questions though:

a) At what frequency does boost control operate at?
b) What is the rated current sinking capability of the different ECU pins for boost control

Any help is greatly appreciated - thanks!

PS: Any chance of getting a new parameters tab that combines boost control with nitrous control so I only have to use one output pin and also lets you adjust the pwm frequency? eh, eh *_*
