Well...I finally went down today to get my predator/custom tune only to find out that the Predator couldn't retrieve the information from my truck's comptuer. After an hour on the phone with Diablo...seems....my truck's computer was reflashed somehow by another programer prior to my purchase (unknown to me). I bought it used and one year old.

Baiscally they told me that a chip can overide the existing program on it...no problem. But the Predator CANNOT overide another program I have never heard of this.

So...after much whailing...I settled with the "black" Diablo Flip Chip and a custom dyno tune.

 

Your dealer could flash it back to the stock program.
