Injector testing

[chris r]

So I just had a bunch of injectors tested. Most of them came out as expected. 

However one set was waaay off. 

A brand new (been sitting for ages) set of seimens deka FI11445 came back significantly lower than expected. (advertised at 750cc) 

I purchased them back in the day from a reputable supplier and I have no reason to doubt they are China copies. 

Seems strange to me that even after sitting the flow could so far off. 

They are low impedance so I'm wondering if the test rig didn't like the low impedance and was packing a sad or some other fuckery is happening. 

Has anyone else come across this or had a similar thing happen?
