"At first I purchased a Superchips Vivid, and it was messing with the electronics such as my traction control, fuel pump control module, and I only had it monitoring until I got a baseline on my brand new truck. After two times of it doing that and working with SC support, I decided to return it for the Edge. I've had it on for a couple of weeks now, and I love it. I would definitely recommend the Edge." —Michael J from South Jordan, UT bought an Edge CS Evolution Programmer for a 2012 GMC Sierra, 6.2L V8.
