First off I did search and I read the userguide from Trifecta and tried emailing Vince but for some reason the emails are coming back. ????

If I go to flash the vehicle and choose any map there's an option for stock/factory tune. If I choose this will I be back to GMS1 or bone stock?

So you're saying you have GMS1 tune right now correct? If so, your GMS1 tune will be swapped out as the "stock" tune once you flash the new Trifecta tune. So yes, if you flash your "stock" tune back into your car, it would be the GMS1 tune.

^^ correct whichever tune you had on the car when you first installed trifecta would be your "stock" tune so like me its GMS1 when i choose stock tune with my trifecta cable

Thanks for the help guys. I thought I remembered it saying it was saving my current tune the first time I flashed it but wasn't sure. The manual threw me for a loop because it said that the stock tune is provided by GM.
