Will a power programmer void my factory warranty? If not what do you recommend I use? Is there any out there that will not leave a finger print? Thanx in advance.

 

To answer your question....YES. A programmer will void your warranty if you get caught with it. As far as recommendations...you didn't specify which motor you have; however, I would recommend Mike @ 5 Star for some custom tunes.

Tons of threads already on this topic.

 

6.2L

 

Nice...I see you tucked that info into your sig now. Call Mike @ 5-Star...I did, and my 6.2l couldn't be happier.

 

a five star tune will do the same ...

 

???

 

 

Void his warranty...

 

Yep...just giving a recommendation if he decides to proceed.
