For the record, i was able to flash a 2004 Tahoe Flex fuel os using 2 CR. When i did this the alcohol content started reading about 10%. Filled up with e85 and it started to adjust the fueling. I was amazed lol.

Are you noticing any weird glitches or communication issues? As I noted before, I haven't experienced any.
For reference, it might be a good idea post your 1 bar converted file as there are quite a few guys with GTOs looking to do the same thing. I have a bastardized file (auto swap with 4L80E) otherwise I would post mine lol.
does your fuel gauge still work?
