Good for the price. Performance program set theft mode when installed, but quick call to excellent tech support got me going! Power gains are definitely noticeable with performance and light tow programs as are improved shifts. Mileage gains with normal driving are questionable at this point. However in all fairness I have yet to upgrade exhaust (a must when adding fuel from tuners if you want longevity and top performance from tuners) and compressor wheel (to eliminate surge). Would buy again.
