you need to get the pc interface kit for it.. that's the usb/serial cable and power adapter needed so that you can connect it to your Windows PC...
http://diablosport.shptron.com/p/u7778- ... t-usb?pp=8then you'll need to install the usb drivers for that once you get it..
then you'll want to download the last update that was made for that predator, which was 9r03 I believe (all predators are now dead and gone - they were all discontinued a couple years ago now...) you can find it and instructions in the downloads section for that model predator...
you'll also need to download and install the DSDownloader program to your PC... this program is used to update the predator, and to import/export tune files from your pc/predator for custom tuning...
you'll also need to download and install the DataViewer program... this program is used to download recorded data logs from the predator to your pc...
if your GTO is an automatic, keep in mind that the predator does not have tcm/tranny support, so you can not adjust any tranny settings like shift points, shift pressure, how quick it shifts, etc... You'd need an inTune or Trinity programmer in order to do that...

once you get that all done and figured out, then you can get custom tuning done from
