Yeah bud i can. i'm not sure how much you know so ill just go over it all.
First insert your SD card into your computer. Some sd cards over 2gb never worked for me. I have had good luck with 1gb cards. With DS Downloader open click on advanced tuning. Choose your custom tune and click add tune. It will then ask you to choose a matching original backup for your tune. Now instead of saving to your computer search for your sd card. Name your file so you know what it is then click save. That should be it. If you have a engine and trans custom tune, you need to create the trans tune like you did the engine tune before saving it. Both engine and transmission tunes will be saved into 1 single file. I dont think i left anything out. if you get hung up just reply here.
