HP Tuners has a repository of stock & usually, modified tunes for our Cobalts. Free to download.
Unfortunately, I don't see any modified tunes for 2010, but there are a lot for the LSJ engines.

I compared it to a stock tune from the HP Tuners repository, and yes, it is a stock tune for your 09 SS.
