ITs just a number, there were three trucks on that dyno that day that were running 500hp west coast tunes none making more than 460hp. My 104mph at 6500lbs shows more hp but alot like mcrat i use the dyno for tuning let the hp be proven in the feild of competition! I could make 450 on the dyno here and make 550 on your dyno there, you see what i'm getting at? There just numbers!
