I got the ProModule & had a few issues at first when installing it that turned out to be because of Chevrolet changes to the wiring on the model Corvette I have but after some tense moments, once I found the right wires with the help of Jack in Support the car fired right up & runs great. Now I don't have to be afraid to drive my Corvette & worry about it breaking down. I reccomend Newrockies to anyone that has GM security issues, at least give it a try! I spent hundreds, maybe more like a thousand dollars on the car in a few months, nothing worked until I found this.
