When I install the module under the hood, if my truck needs to go in for warranty work, and I take the module out, will they be able to tell if the truck was chipped prior to me bringing the truck in?

 

No.

 

not necessarily true, there is a lot of hearsay on this subject, all of which I can not substantiate

I have been told by a tech however that there are 'U' codes which show up which are codes showing that factory parameters such as boost etc have been exceeded. Whether they look or care is up to the tech.

 

Yes, a good tech can tell if it has had a module installed. Its next to impossible to remove all traces of a module or any power adding device. Bottom line, if you value your warranty in any way don't mod the truck until the warranty is gone. Its up to you, but I wouldn't gamble on it myself, I mean you paid for the warranty why jepordize it.

 

Yes.

Gotta pay to play.
