Ok today I tried to download a stock injector/aftermarket turbo upgrade for my smarty-just to see what it does. I found out real quick that I have no idea what I need to download and in what order. I did a search here and on another site and found a post that said I had to download 7-zip file which I did, and I had to unzip this and unzip that... I have no idea what that means. So can anybody tell me how to go about this in plain english?? thanks
