May be best off just calling them to get all your questions answered. My understanding is that the Sidekick X can run pump fuel for lower boost settings, but has a switch or option that you can select that allows you to run 10lbs......but would need race fuel. I have never heard anything about the Tial comment. If you are riding lower elevations I think the box automatically compensates and your boost would lower. But like I said, may want to just call them.
