Default Injector testing

I tested mine cold while under the plenum all were very close. Then tested them Hot and all were very close 14.5 very hot then all came down to 13.5 as engine cools down. Did this testing between the pcm and Secondary relays.
The car runs fine and Smokes 'em at will.
But just because they ohm correct is it possible they still are not 100% on the flow??

you have to check the injectors individually at the injector. Flow has nothing to do with injector coil performance. The only way to check flow is on a flow bench. But if you are going to take out Multec's to check them you might as well replace all the injectors at the same time. Remember Mutlecs are not alcohol compliant so the E10 in the fuel today is ruining the epoxy seal inside of the injector causing fuel to seep into the coil housing. This will eventually short the injector out.
