Resistors and Injector Dynamics?
 

Ok so i've been doing quite a bit of reading on Injector Dynamics injectors lately which i'm running. In the reading i've seen people say that no resistors or injector drivers are needed to run ID injectors on a FD with a PowerFC? Is this true? Because I got my ID injectors 2nd hand and they were prewired with resistors in line which is how i have them setup on my car. Could this be why i maxed out 725s/1000s on just 12psi? LMK.

Did you check the impedance of the ID's?
I can see LO's with a resistor but not HI's with one.

I'm running 725s and 1000s, but as far as i can tell all ID injectors are high impedance?

Get rid of the resistors, they aren't needed.
