Product came fast and worked great. I would always prefer autoanythjng over its competitors.

This is an awesome product. Installed right away and had a very noticeable difference just on my stock 6.2l gmc. I don't have anything modified yet but this still gave it bigger balls. The only bad part is even with the expensive price, you can only install on one vehicle at a time. You have to restore factory tune on last vehicle before new vehicle is set
