Traded in my 09 SG for a 2012 EG Limited a few days ago and can't stand the stock exhaust. The consensus is upgrading and tuning is no problem within break in as long as I don't go apeshit on trying to fill in all the cells during my tune sessions.
My 09 ran great with my master tune so here we go again with another 400.00 dollars for a new module. Good thing my V&H rounds and SE A/C could be reused to save a little.
I've done the tts updater and found 2 sections on 2012 touring maps.
One was:
2011-2012 DBW Touring Closed Loop and i'm looking at DTA044-03 for my 103 A/C, Factory 2:1:2 exhaust.
The other section below it had:
2010-2012 DBW Touring Closed Loop and there it has DTA009-03 for the same 103 setup.

I'm not sure what base would be best. the one that has 2011-2012 were just added, so probably the best to start there with the DTA044-03.

Any opinions?
