Thank you.

I have a 17 GMC Sierra and the i2. Is there a side by side comparison between the i2 and i3. I'm wondering it is even worth "upgrading"?

Ok, thanks.

Hello Mike,

I know in the past you have said the 2017 GMC Sierra 8 speed transmission can't be tuned. I was wondering if there have been any movement at all towards tuning, or is it a lost cause. Thanks if advance for any feedback that you can provide.

Mikel,

I do have a windows system I can try it on first.. If that doesn't work then I'll post up you info you requested.

Thanks for you the quick response.

I'm sure this is discussed elsewhere, but honestly I don't have the patients to go searching for the thread.

I've been trying to update the this POS for the past 45 minutes and have made zero progress with it.

Actions taken so far - plugged it in, went to update folder > MAC > update. it did its ...

I was glad the read about the new canned tunes have been released. In the release notes it only says TCM update for the 6 speed transmission. Any news as to when the 8 speed will be released?

Are you guys going to continue to try and break the TCM encryption?

it would be nice if the tune is released soon and hopefully it includes the TCM. I really dislike the 8-speed manners.
