zixxer- looks good buddy!! I'm glad you are happy with the engine. I just wanted to throw a couple tuning tips at you to help you find the tune on it. I don't know what you are running for clutching or what the smoke look like down low but it sounds a touch lean on the bottom and a little rich on top which is a common mistake most engine tuners make. The tune doesn't sound bad but it should definately have more pop down low. It sounds flat on the bottom and doesn't seem to smoke until the midrange so what I would do is richen the LSN 1-2 hours at a time and lean in the HSN the same until you see a solid smoke trail from the time the truck responds to your throttle input until it hits peak rpm. The HSN not only dictates how much fuel is delivered at WOT but it also controls how much fuel is allowed to reach the LSN at low end operation so if you have the HSN too rich, it will give a false indication of a rich bottom end and you will feel the need to lean the LSN when in fact the HSN needs to be leaned in and the LSN richend to balance the fuel signal at all rpms. Try that out and report back to the engines response to those changes. Obviously you will most likely have to adjust the idle accordingly but that engine has alot more hidden in that thing as far as low end grunt
