If you test the grey injectors at 100% duty cycle they actually flow about 440cc. The yellows flow about 520cc.

But injectors are rated at 80% duty cycle which is when they flow 380cc and 440cc respectively. If you read up the american sites they call the grey tops 440's and the yellows 550's.

The Grey's are still rated as 380's though.

I flow tested some 740cc injectors and they flowed about 830cc's at 100%. I think the standard for them is to rate them on what they flow at 80% as they're not supposed to be run at 100%.
