Told him to replace the battery and I've had no reply since, not sure if he's tried it at 175psi, but I've told him he should get the pressure up to 175 - 180 psi and work with the dwell from there I've even told him that if can go to a max input of 200psi but then he risks spiking the noid.. I know he's set the dwell beyond the max point which will give him problems
