I bought the aem ems series 2, 650cc injectors and the 3.4" pulley. i have a few questions:

1. do i leave the adjustable fuel pressure regulator that came with the ctsc kit there? is there a certain way it should be adjusted?

2. (yes or no) i just remove the stock ecm that came with the ctsc kit.

3. can i use an aem wideband as my o2 sensor?

i appreciate everyone's time and answers

 

1. You can remove it, there's no point in having it if you already have an EMS/Injectors.

2. Yes, remove the ECM, the EMS will take care of clamping the MAP.

3. Yes, the stock O2 sensor is a narrowband and the EMS doesn't use it anyway.

 

do i replace the primary or secondary o2 sensor?
