I was in Advanced Diesel in Anchorage getting some work done. Just as fuel prices were going up. I had them install an edge box in my 99 2500 4x4. he said it would improve my mileage and power. I was susceptible at 1st but he has never been wrong before. I could not believe what happened next. When I need the boost in power, it's like hitting a JATO bottle. you actually can feel the power. then I noticed that my in city driving went up about 15% and my highway driving mileage went up about 20%. I hauled a 16ft trailer (Loaded) up to the Arctic Circle and averaged 16. 5 MPG. There are many long uphill climbs on the haul road and it went these hills like there wasn't a heavy trailer attached. EDGE is awesome.
