Bought one of their cold air kits and a xcal3 for a coworkers 2008 Mustang . After an easy bolt in and loaded the new tune ,we couldnt belive how much it woke up his stang. It went from not spinning the tires to roasting them now! Just wanted to give a big thanks to JDM for all their awesome products and customer service. I think my friend is now hooked on modding his Mustang lol.
