The reason I had to pay for a segment swap was I switched to an Auto OS, where my original OS was 6speed. I thought the 6 speed OS might have been causing the problems. I also was seeing other weird issues, like not changing idle speed from P/N to in gear, but it would change the airflow, etc.
The reason this is just now surfacing is that OS has the 4L60s set to 256 and the 4L80es set to 50 mph in 2nd and 75 in 3rd.
Also, you can note that Bluecat Posted where in the bin file the tables are, and he is OK with sharing the information (to the whole LSx tuning community, not just HPT).
