i have a power fc,,, and right now they are on the stock high imp injectors

i want to put 2 1680cc on the secondaries, but they are low imp

can the power fc handle the low imp or would i have to wire resistors? would the tuner be able to figure out the lag time and all that stuff?

i have a set of 800 and a set of 850, but i dont think that could support a gt4082 on stock block???

 

If you use the low impendance injectors with the PFC, you will have to use resistors to limit the current to about 1-1.5amps. But this requires running a larger lag time to make up for performance loss.

Or use the FJO driver which will solve the problem without reducing the secondary injector performance.

If a tuner can't resolve the problem, then they are not tuners!

Large primary injectors are a pain to idle tune. If you engine is not a race engine, use 500/1680 which is good to over 450whp.
