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.

It will only be a matter of time before the door is opened.

Looking forward to your feedback on the Corsa when you get 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.

I emailed them to clarify. Their description only says Sierra and Silverado. Like the Pulsar LT, I doubt this ecm works with the Tahoe/Yukon/Esky.
