injector testing

Postby DodgeFreak » Sat Mar 22, 2014 11:54 pm

I'm setting up department stage 4 injectors and I'm wondering if they are supposed to chatter. Pop pressure is good but it doesn't chatter like the others I've set up

Yes, they are supposed to have the same chatter as you would be used to. Do you have the capability of cleaning them?

Ok.... probably best to have a shop go through them. As they are supposed to have a chatter to them, if not then something is wrong.
