    Did a calibration test the other day and the amounts were way to high, way over the variances listed for all nozzles. Appears there is to much pressure, could the unloaded valve be the culprit because as far as I can tell that is the only way an adjustment could be made to the pressure. The nozzles are fairly new, and in the correct placement so it's not a wear issue. Anyone else have this problem ever?

    RPMs are as should be too.

    Mine is a 2010 model, 425 hrs and I have the same issue as you describe. We just do our mix according to the rate out of each nozzle.
