1) The track has unleaded race fuel, 110 leaded, 112 leaded, and pretty sure methanol.
2) See the schedule. I am not directing the race, nor do I agree with the layout. I can not positively say that there will be time on Sunday for test & tune runs. They are trying to make this a big program, but I don't know what the expected car count will be. You can always try calling or emailing the track, but I would not expect them to answer necessarily. Or have an answer if you do get someone on the phone.
