"Great customer service and fast shipping. The predator added some serious power in addition to my magnaflow exhaust, air intake and throttle body spacer. I only have the programmer on the 87 octane tune and the results are very noticeable. Can't wait to try out the other tunes! I would highly recommend this product and site." —William M from River Edge, NJ bought a DiabloSport PC Interface - USB Cable Kit for a 2009 Chevy Tahoe.
