Yeah, you can get an upgrade called the speedloader with the 6-gun. it wires right in the line comming from the box to the 6-pos switch. It adds an additional 28 hp if i remember right... It takes 350 degrees from watching my gauge for it to kick in. You can feel the extra power when it hits that mark... you don't need a gauge for it to work... Also it will de-fuel your truck when it hits like 1400 degrees or so.
