How long can you run 720 secondaries without dyno tunning and SAFC? Do you even need to?

Mine SAFC has been zeroed out for about a month now because I lowered the boost.

You can run it like that for as long as you like having less power and high fuel consumption.

If you install the resistors at the injectors, you can install them into either of the injector's two wires for the same effect. Alternatively locate the four injector wires at the ECU (using the wiring diagram) and install the resistors there. :)


bumped.....so lets say if u wire it near the ECU.....u would convert all 4 low imp into high imp harness...what if i want to just conver the secondaries and keeping the primary stock high imp..would it give me better throttle response?

You are only supposed to put resistors on the injectors in which the resistance is changing. If you are only changing secondaries only wire/solder them in at the 2 ecu pinouts for the secondaries. If you are changing all 4 injectors do it for all four.
