Default Lowers torque converter stall

I have a 4l60 and was running it with a 2800 stall torque converter and I just had it fixed that the transmission pump went out and decided to change to the stock converter because I didn’t like the loose feeling of the other one
would I need to go get it retuned since it was tuned to the 2800 stall?

No , if the tuner compensated for the stall if it was kinda loose the shifts at wot might happen a little earlier and the part throttle shifts a little higher but wont hurt anything. .
However you are likely removing the single best performance mod you can do. If the trans shift ponit at part throttle are set right a 2800 unless its a cheap junk converter should feel pretty close to stock just driving , Raise part trhottle shift 10 to 20 percent, Mine which is a 2800 and running 3.08 gears feel pretty much stockish at normal driving in a 4400 lb car . Now with the stock part throttle shift points yes it would feel a bit mushy but even then a 2800 should not be bad .

For a 2800 stall speed to feel "loose" it must either be a really junky/cheap low-efficiency unit or you must have a really tall gear with some really tall tires (or some combo of the aforementioned).

Your tune does not need to change. A common tune change for a high stall converter is to reduce the misfire sensitivity. That won't hurt with a stock converter.
Agreed that if you thought a a 2800 converter was loose, it was a junk/cheap unit. What brand was it?
For comparison, I have a top quality Circle D 3600 converter and I can accelerate briskly from a stop without the revs going over 2200. Of course if I mash it, it jumps to 3600
