The injection pump you have does NOT have an external adjustment to set the fuel flow. You have to remove the top cover off of the injection pump. Then you have to have it in just the right rotation to reach down into the pump to tighten the screw on the retaining clamp that controls the pistons stroke. I hope you see that this is not easy to do. Also to do it without a Dyno is just asking to ruin your tractor. I would not recommend turning your tractor up that much. When you increase the engine horse power then the rest of your tractor needs to be able to handle that higher horse power. Your radiator is just one part that has to handle more heat.

If anyone other than me ran it I could count on the turbo and valves getting burnt. I finally just turned it back close to stock.
