question on mods and tune

[Longshot270]

There is a difference with the commercial intake and the gotts mod. With the aftermarket intakes, the pipe diameter increases around the MAF sensor letting more air to get in than the computer knows to compensate for, causing the lean conditions. If you still have the MAF sensor in the stock surroundings then you will be fine.

^^^ What he said, and, I don't think your truck has the "lean" problem regardless of the type intake you install. This problem really surfaced with the 04+ model year.

I thought it would be fine but just wanted to ask. I was told only the 2004s had the problem but just wanted to be safe my truck runs good just worried about leaning it out after reading the article. thanks.

Yeah, I also think the newer ones are more likely to run lean because of the emission standards, less chance for failure on the sniffer test if they aren't running on the rich side.
