vista may be your problem,but ill tell you how i did it,first did you download the program to put tunes in the predator?its on the download section of the site,find the one for the 7130,then once you have that installed,go to the sticky on the predator dodge forum and click on the extreme 12xxx one,it should come up with the save this file option,save it to a folder or your desktop,its a drd file,then open the diablo program and click send tune to predator and it will ask you where it is,tell it where the folder is and conect your predator and make sure the baud rates are the same on the diablo program and the predator,mine was from factory but some are not i guess.then it should go,it takes like 5 seconds to go into the predator,are you using a serial to usb cord or a serial cord?do you have the proper power adapter too?i wish the predator was usb and needed no external power but hey,you dont plug into the pc that often i guess,try all that and let us know,i really want you to get this workin,you will love the tune,then once you get it and you plug it into your truck you will go to perfromace tunes and then costom tunes should come up and choose that and then it will give you 4 options,ext,ext with less timing,ext stack and ext stack with less timing,choose extreme rkl with timing and then 2 minutes and your burning rubber dude,
