Long story short, a long time ago I decided I needed to use COS 5 for a full bolt-on car. No idea why. Now I want to go back to the stock OS which is 12212156. Is there an easy way to copy all the changes I made in the COS and paste it to the stock OS? I read about the create/run script function but was a little unclear about the details. Do I just load both tunes, create script, load stock tune, run script and save? Then take the new tune and program the PCM operating system and calibrations? Thanks!
