Which cam will work decently with stock magnum tune?

I have ran a similar cam as the one you listed. Similar in all specs. In a 95 dakota 2wd. And in a 5.2 it didn't start making power until above 2,000 rpm closer to 2,500. I ran a mopar performance computer without issues but that was a obd1 ecu.

Guess it depends on what your wanting the ram to do. For better all around performance maybe a comp 20-608-9 or the comp 20-612-9 maybe the 20-602-9

Or try hipotech they have some grinds for 4x4 or heavier truck applications

On my dakota I did the slot the crank sensor mod and advanced timing and also set sync to I believe +3 maybe +4

Whatever route you go. I wish you luck
