Does anyone have any experience with a PDQ Volumizer control modual for the 6L deisel. Mine works great better mileage, lots of power but sometimes i get a no start condition. Always eventualy starts but is getting to be a pain. I thaught it might be issues with the turbo or EGR but all issues were just delt with at the dealer. New turbo, EGR and programing(i beleive)etc.
