I am putting some stage 4 jammer injector nozzels on my injectors. What do you think the pop off needs to be set at. I had some stage 2 last time and set them at 310 to pop off. But i have heard a bunch of people say they need to be set at 300 anyone have a clue????

Come on guys surely someone puts their own injectors together.

I have always set them at 4000 psi, Im assuming you are talking BAR?

Well the guage on my tester is in BARs. There is no psi. Do you mean 400 bars??. The set that is in my truck right now are set at 310 BARS. I have heard that 300 is were you want to be. But it doesnt hurt to ask.
