im about to order a custom chip from psp, it asked what computer code. i have a 99 lightning. should i go with the cux1? and what does reflashed 00-99 mean? thanks

 

If you have taken your truck into the dealorship (wow, I cant think how to spell that right now, I know that isn't spelt right), and they connected the NGS tool to it, the NGS will have automaticly reflashed your computer for CUX2. But being a 99, and if it hasn't been reflashed, then it is a CUX1.

 

ummmm,,,,, ??? i prefer doritos

what a ngs tool?

 

The NGS tool is a computer that dealorships have that will read any codes, run a quick diagonistics, and reflash the PCM (Computer in your truck) with the latest and greatest program.
