New to this site and new to my truck. Have an 04.5 with the LLY engine. Have been reading a lot of posts here the past couple of days and obviously I have a ton to learn (can I get a hell ya). Without asking you guys a 100 questions where can I search to get info on my truck. I am stock and was considering one of these chips that are out there but am really clueless to the positives and negatives and what are the best brands. Also just looking for basic info on maintenance, air intake systems, etc. Would like to polish my skills before I get into to many discussions. Thanks in advance.

You can try using the seach button under and enter chips. I found this:

I am sure that there is a bunch more out there. :)

yes the search function will provide you with more info than you care to know. since you have an LLY, try searching for posts on the TTS or edge in the LLY forum. also review eric's maint. list at the top of the topic list..
