I bought an Edge Evolution CS tuner for my 05 Avalanche at a great price, a lot cheaper than any other place I looked. Delivery time was amazing it tooked two days from the time it was processed and it was over the Christmas holiday and it still made it to my front door in less than a week with regular ground shipping. Customer support is awesome and fast at answering any and every question you have and remedying any problem. Great site and great service. Will definitely recommend to others and use again in the future for all my automotive needs. Thanks Autoplicity.
