I bought a cobalt SS maybe 3 months ago and it's got a street tune (opinions on this plz) and smaller pulley (3.0), and tc swapped tranny and some exhaust work. I was wondering if I was to go stage kits with this, would I need to tweak things with this swapped tranny or is it the same gear ratios, etc etc? Thanks any and all help with this would be helpful!

the tc transmission has a 3.82 final drive where the sc is 4.05. the 3.82 trans is actually the weaker of the 2, because of the taller final drive ratio more stress is put on the transmission. however with normal driving with a decently modded sc shouldnt break it.

you wont have to make any other tweaks for it.

Okay so what are the benefits from the difference in final drive ratios and also is it possible he swapped trannys and kept old F.D.?

its possible to swap the final drive ratio, it however takes full disassembly of the trans, special tools, its a lot of work, so its unlikely it was done.
