Hi Larry,
Seems most don't like to go above 85% duty cycle. However, Protomotive go much higher than that. The problem is as I said earlier that too big of an injector at idle (therefore at a low duty cycle) will cause a poor spray pattern. This is why Ruf used two injectors per cylinder with only one being used for low rpm and idle.
