edit**** my stock tune file was lost in my old computer and my current OS is already a 3 bar. is it possible to reset the ecu to stock settings using tech 2? at that point with the stock ecu, I could properly 80e segment swap, then switch back to the 3 bar OS. im trying to avoid wasting yet another 2 credits on something that doesn't work out. ive heard of tech 2 working?

you need to find one with the same OS number
You need to segment swap with the stock OS.
Good luck making it work with an already upgraded 3 bar OS installed.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Ahh so I’m screwed pretty much, wasted my credits on that stock tune file. I was thinking another option would be to make the 2500 tune 3 bar, and transfer my current VE’s over to that tune. But the 2500 tune doesn’t have the option of 3 bar... cool. ��
