For those interested in learning how to tune, and seeing what your stock parameters are for your GM vehicle.
Download EFILIVE http://www.efilive.com/download.aspx and then download the stock tune for you vehicle. http://www.holdencrazy.com/EFILive/stockTunes.php
You can get an idea what the different settings are before you modify them with the Predetor.
It has helped me out quite a bit. Just thought it might help some of you guys.
Have fun!!
