The biggest benefit of using the Edge Revolver chip over the competition is simple: Edge makes the BEST Diesel tunes. At Edge products, diesel performance is our passion. Every day we install cool new toys on our in-house diesel fleet in order to create an extraordinary driving experience. Our engineers build the products for people like themselves- Diesel Nuts! You can expect better tunes, better performance gains (level for level) and better drivability from an Edge Revolver chip than any other chip around for your 7.3L. We are proud diesel people, and we set out to prove it- just look at the dyno sheet!
