Cheap Chinese knock-off of a 3-port MAC valve.
Just use values everyone else uses for their GM MAC valves - these may or may not work, it's a cheap Chinese product after all.

please could you share the link to one you are using?

This is what a legit one looks like.

Please note that the bag of accessories shown have been added by the company marketing it as a boost control solenoid.
The valves themselves just come in the box alone from the manufacturer/importer.

A good frequency of the legit 3-port MAC valve is 33Hz. This gives an approximate duty cycle range of 20-80%

So to answer your original question... Try 33Hz?
