I just installed a predator on a guys truck, Wouldnt load, loaded all the way through the backup and fried on the download, wouldnt ever build a tune then lost the vin number and wouldnt work anymore .... on ANYTHING! thank goodness for tech 2, it saved my butt and i smacked a edge juice with attitude on it! i will never buy another predator! I tried one on a lly a week ago and had problems, sent it back, just called and told them to keep it!
