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.
