What i mean is because the pistons are so small they dont seem to like larges changes in pressure when linked to lage plenums the sealing matirial gets hammerd and leads to inconsistancys which is why i hypothsiesed about the manufactures reason for useing two regs in tandem.
I removed the huma reg i fitted to my R10 for this reason.
