If i remember it absolute correctly the only stuff i did install in the Hump was Collector as it is needed to pick a certain item up (cus the pre-installed sub one takes an eternity to finish the job but you can stay cheap with top Sol or Drac one to save even more cryo); Afterburner as you will need it a couple of times; Inverter (mostly for the minefields) and RD if healing was needed.
As the mission itself not really requires any fighting you can do it with most items missing what saves already a ton of cryo for this part alone as the actual "undercover" is not as undercover as it should be considering that your Hump is surrounded by a bunch of other pilots guarding it and wrecking everything that crosses the path during the mission
