Well, first of all welcome to the forum. Second, there is a lot of info regarding tuning on here to help get you up to speed. Basically as of right now, only Uprev is supporting the Z. Cobb only supports 2009. Uprev offers mail tunes as you are already familiar with. Also offered are tunes from Uprev tuners, but you have to go back to them for adjustments. Lastly, there is a tuner version that allows you to pay $50 for a mail tune, or take it to any competent tuner and have it done. You must download the software from uprev onto a laptop and plug the cable into your OBDII port and usb in you laptop. You can do diagnostics, read & clear codes as well as tune on the fly. I recommend checking out their site to get up to snuff on it.
