Decapped fuel injectors flow results I am currently running some 65lb FAST injectors and running out of fuel around 14lbs on a 5.3 S475 setup on pump gas. So I jimmy rigged a flow tester to test some flex fuel injectors from a LC9 I had laying around . After decapping them they flowed around 880cc/min which is about 86 lb/hr @58 psi and 800cc or 76 lb @ 42 psi . Searching around most people have had higher flow numbers in neighborhood of 90-100 lb/hr . Also 6 injectors flowed within 1-2% of each other but one flowed 5% over and the one was 5% under than the other 6 . Is it safe to run them as is ?

Yes I did , and they ran awesome . Perfect afr control at a 600 rpm idle. Ran 14 psi of boost on pump gas and water meth for a of year or so. Decapped some ford coyote injectors after which are 100 lb/hr,, running those currently .
