The Sietch will be brought offline for HPG systems maintenance tomorrow (Thursday, 2 May 2024). Please remain calm and do not start any interstellar wars while ComStar is busy.
May the Peace of Blake be with you.

Then, you can work out what the limits are, and how much better you can get from there.
More distance? More gravity tolerence? Less power issues? The sky is, quite literally, the limit.
If I'm going to be a little more serious, I'd look at improving Jumptech in general.
There's been missjumps that went more than 60 lightyears, and many related things. Better Jumptech makes than standard.
