There are a lot of crazy ways to make big power out of a ZL1 (and trust us, we’ve tried them all!) but for the enthusiast looking for reliable, easy, and repeatable horsepower, there is no package we would rather recommend over our Vengeance Racing Stage III ZL1. It's simple, utilizing little more than a set of upper and lower supercharger pulleys, a quality camshaft, a full exhaust, and a good heat exchanger to keep IAT’s under control, but the VR Stage III is the go to package for the driver looking for big power without big headaches. The ’13 ZL1 shown here is a perfect example of the VR Stage III automatic and shows the potential of the package...

Oh, did we mention this ZL1 came and left with the dealer tags still in place
