Elite: Dangerous PvE - Mobius

I have posted on the optimized RatSprinter RAsp (47/51ly) here.
Since Ratting means mostly playing in Open during Rescues, and optimizing means scaling down almost everything to D-grade or lower-calss A, I would like to know very much which engineer upgrades do NOT affect jump range negatively.
Especially:

Dirty /Clean Drive Tuning to be able to run in normal space if required;

Shield strengthening to get a bit more out of D-grade shields.

Thanks!

I didn't lose any jump range on the cutter or python with dirty drive tuning.

Anything that increases mass of a module would be my guess.

The sturdy mounts increase mass, as does anything called 'Shielded', other mods can throw up a random mass increase (or indeed decrease) as well.

Conversely, anything with 'Lightweight' in the title decreases mass and therefore increases jump range.

Depends on your mod and roll.
I assume this is pretty basic but anything that adds mass to your ship will reduce jumprange.

I can confirm that Shield Strengthening right now ENHANCED my FSD range, got a good roll on Optimized Mass and it went up some 0.5 ly ... yay
