What Cummins 24V chips/ tuners/ boxes/ you like or not?

Some of you already made some suggestions on "whut'tado" with the 01 Cummins 24V I just bought. Anybody, opinions on simple stuff, "non harmful" LOL to boost things a bit?

"Turbo elbow?" Still researching that
"J hook" " " " "
Some sort of "box" don't want to spend a TON of money...................

This is a 5 speed by the way so don't need stuff for an automatic. Probably won't swap out for a larger turbo, and know about the lift pump nonsense, and am looking at that
