10-16mm???? Thats gotta be the dumbest statement on this board. Deere never used 16 mm plungers in any of thier pumps. Deere never made a 6X12 tip either. Obviously you have never rebuilt or made CNC parts for the 2 cylinder pumps, because you would have known that statement is false, and cannot be done. The barrel walls would be paper thin....or not even a wall. Deere used a 10mm and a 13mm barrel and plunger assembly in the 2 cylinder era, nothing else. The reason the 10mm flow the same as a 13mm on the bench is because the helix is ramped down on the 13mm plungers. All Deere wanted to do is increase pressure and injection timing by going to the 13mm plungers.
While there are 15mm barrels and plungers being made, the wall failure rate is inevitable, to thin to keep plungers from seizing over time.
To answer the original posters question correctly, yes spending money on pumps and injectors is one area to improve. Which head do you have? Is it a later black dash tractor?
