Review on Hypertech 3000 Energy Spectrum Programmer by Shawn Quick

Before you can do anything, you must connect it to your computer and update all files on the device, which takes about 20 minutes. To download the software, install and update your device. After that you can use the factory settings on your car. This device just freed my American horses on my Chevy truck. Got it on sale and it was definitely worth the price, has a few settings you can customize or preinstall. Will update my review if there are any changes.
