Just found a site that that does Dynamic Injector flow testing. Some of the things the testing can get:
Dynamic Flow vs. Battery Voltage
Dead Times/Battery Compensation Values From 6 to 16 Volts
Maximum Allowable Duty Cycle/Pulsewidth vs. RPM
Horsepower Potential vs. RPM
Minimum Linear Pulsewidth From 6 to 16 Volts
Dynamic Flow Deviation Between Injectors
