Nick Priegnitz, CEO of Duramaxtuner / Calibrated Power, recently got a new truck in the shop. A gas GM 8.1L big block and well he wanted to put it up against our tuner Tim's DIY 'Til I Die LB7 to see exactly if the diesel is better than the 8.1L....

Nick goes for horsepower, fuel economy, and cost of mods to see where these two end up at. Take a look! Anything you'd like to see, drop a comment on this video.
