New to the forum but have been reading it a lot. I just got an 06 HD w/82000 miles on it. Previous owner put what looks like a Spectre CAI in it. It's got a lot of power but now it's throwing lean codes at me. From what I've read on here so far I either need a custom tune or need to go back to stock. What do you guys think?

 

Welcome to the site, it's great to have you here

I'd say go back to stock and get a nice tune! Stock intake provides more than you need and it's a cai. Welcome to the forums. Check out the 04-08 section and post in there. You'll get more responses
