When replacing the apps on a 2002 once installed does the apps need to be adjusted?Thanks in advance for your help!

What kind of Apps did you install. Timbo, auto parts brand, or factory replacement?this ought to be in the 2 gen forum and not the 911 support forum.

Follow the instructions that came with it. I know when I put on a TIMBO unit it had specific instructions for setting it up!

Does the factory replacement does not need adjustment ? I am thinking about getting one off eBay and it have long instruction to follow and some what complicated

I dont think the factory replacment needs adjustment but I wouldnt buy one of those either unless its real cheap. Why not get one from Tim? http://www.dodgecumminsapps.com/

I plan on getting one from Tim, from what I have heard, his is the best out there.

It is a very good product and easy to install.
