So since the ECM is locked by GM, are we only able to do CAI and exhaust? I’m getting the new Corsa exhaust for the 6.2 but would really like to get more out of it.

You can purchase an unlocked ECM from Whipple Superchargers, HP Tuners, and a few other places. I have seen them available for purchase. They are running arounf the $700 mark for an unlocked ECM.
