My Asp will jump 55lys on a full 16T tank, 56.9lys on fumes. There is still room on the FSD to do better yet, maybe after 3.0 I'll work on that.
Nowadays I explore in my 59ly DBX.
Mine can do about 57.3 Ly on fumes but I've seen one or two which managed 60 Ly but I bet you they were so stripped they didn't really serve for exploration, if I remove my SRV I can get up to 58.3 Ly which I once needed.
