Kinda hard to explain, but i'll do my best. i installed the evo and i noticed the engine now has a ticking or knocking sound, it's also louder, sounds like it's coming through the firewall. I installed everything to the "T" according to the instructions. I was maybe thinking I didn't get the pyro tight enough but it was plenty tight, the only things I could think of is i messed up tapping the pyro, or the sound is coming from the grommit were the cable runs through the firewall. it's kind of annoying, but I'm more worried that i did something wrong anyone have this happen??
