The Procede only sprays the meth when called upon. The meth tune is only active if the meth is spraying. As soon as meth stops spraying or you run out of meth, the Procede defaults to Map 1, which is a without meth tune. All mods are a gamble and tuning is at the owner's risk. ESS has a proven record for reliability as does Vishnu. Probably would make a pretty good combo package but you'd be a pioneer in testing and risk. I'd love to have someone do this before me.
