If you want to be given the cold shoulder and treated like livestock, this is the shop for you. Whether they are God's gift to the tuning world is open to interpretation. Their scheduling is disorganized, and their attitude clearly needs some "tuning" since I am not the first to post a disgruntled review. CMS is a good example of a shop who grew fast due to their forum presence, and the extremely high demand for LS tuning and modification services in the Socal region, but then let its popularity get to its head. Take a look at the attitude and arrogance behind their responses. Believe me there are plenty other unhappy customers who haven't found their way to Google reviews. Cue the "we can't find you in our customer database therefore your review cannot be substantiated" !!!
