I know your a fan of RC engineering HDDP, but I have seen thier set-up and heard about how innacurate it is from other customers, and you don't want to know about the genius operating the equipment. One guy went in with one injector got it tested, then came back another day to double check the quality, and man was it way off on the retest like 20% off

You can do the same if not better job testing your own fuel injectors at home, just make up a y-harness that feeds signal to the cars injector and plug the other output of the harness to the injector your testing, run the car at the rpm you desire and then measure your extra injector that's being fed signal into a graduate. trust me you can do this yourself cheaper than paying RC engineering.
