vibration is getting weirder
Hi everyone. I just installed an S&B cold air intake this morning. I started the truck up and everything seemed fine until I took it for a test drive. The intake does seem to add a little extra oomph and my average fuel economy is .8 better than before but the vibration I described in the previous post is 10times louder. It happens under the same conditions but at first I didnt even realize it was the same noise because it is so loud. I assumed it was the intake drone that I have heard the S&B has sometimes and was trying to think of a way to deaden the vibration in the air intake when I got thinking about the vibration I was already experiencing. I set my gryphon back to stock and all the vibration/droning went away. So now I am wondering if the noise I felt/heard in the original post was coming from the factory intake and the larger more resonance prone cai tube just amplifies it. I really dont know. Tomorow I will try two things first is to rev the engine while in park with the gryphon set to 87 tow and see if it makes the noise and then I'll try test driving it in tranny only. If anyone has any suggestions I could sure use the input. I'd like to make sure I'm going to keep this intake before I send in my hex code.
