The ideal tank input pressure is around 550 I believe. I am just basing this off of the Ninja SMP series regulator they made which was supposed to be ideally suited for the Ego, Geo, and some other markers. I am fairly certain however that you can run it at any of the adjustable pressures without issue. I run my Geo 3 off an SLP tank and it works fine.
