TCM Tune File attached.

I'm using this version:
CROM version = 'gm_can_gas-1r09 06/05/2012 12:09:48 PM boot3'.

So, after i've got the tune installed, I just go into the parameters and turn off the limiter? I have not seen an option to turn it off.. Assuming I find it, doing this won't over-ride ...

Shouldn't the pre-installed diablo tune remove the stock speed limiter? It did on my 2011, but it's not working on my 2012. I have not found an option to delete it via the change stock tune method either.

Also, I've selected the "firm shifts" option for the TCM tune and it's acting a little ...

I'm having the same issue, not able to install TCM tune, only PCM.

2011 Silverado 6.2L 2wd.

I've attached my stock tune backup file and the installed diablo tune. Any help appreciated.

Thanks,
Jerod
