I am giving it 5 stars even though the instructions for getting custom tunes are not there, however the salesman told me about the Diablosport.com Forum and that has a plethora of advice and guidance as well as a tuner named Diablew and they have been awesome. this is simple and very effective just what you need to wake up the 5.3L V8 for better drivability & mileage Auto anything price matched from a competitors site and beat that price by another $25.00, Great device and an awesome web site...
