Well, its been over a year since I had a chance to put my truck up on a dyno, and I just so happened to have a chance to have at it yesterday at Sasquatch diesel's "search for power" event. I really wanted Dunbar's too, since that seems to be the standard that everyone sets their mark by. So long story short, David ran my truck to a best of 411.68 HP and 790 lbs of tq. I've got a print out of it, but no way to scan it at home tonight. I was running my Xrace file from innovative. My power curve looks beautiful on paper, the HP doesn't exactly peak so much as its a plateau. From 2500 3800 RPM the truck is near or above the 400hp mark. For no more than I have done to it I'd have to say I'm happy.
