I was very scared at first, the module is made of plastic and trying to secure it into the ECM was nerve crunching at the thought of snapping the plastic. After a hard start, the module adjusted the factory settings and damn, I was off. At an average I dropped off a second and a half on my 0-60, haven't tried the 1/4 Mile yet. I'm interested to see. Any Fuel Injected vehicles NEED this chip!
