mixing low and high impedance injectors

I'm running the stock high impedance 550s on ms2 v3, I have a pair of 1600 for the secondaries. Is it simple as putting them in with inline resistors and changing the setting to 1600 on the staging menu on tuner studio?

Even simplier. 1600cc injectors are 4.5 ohms which is high for a low Z injector. Low-Z is typically 2Ohms.

I have tested a pair of them on a V3.0 PCB driver and they do not burn anything out. Don't use resistors at all...

Stage them in at 75% duty, 5% duty hysteresis. They duties will be so short and so infrequent you will never have a problem.
