Running the Yeti Stage IV Hot tune along with an adjustable Diablo Power Puck and a Suncoast Converter and cannot make it shudder under any situation including towing. The Suncoast will handle anything you can subject it to with the 2.8 CRD, its tough and the way to go if you can swing the price....

What does the diablo power puck do, just increase fuel rail pressure? Does it effect boost? If so what boost are you running and how much smoke are you getting with both the tune and puck combined.
