As long as you have the latest version of the tune tool the 2 bar COS option should be available to you when you open your tune. Check the 'Upgrade OS' tab. You can then select the 2 Bar COS and click 'Apply Upgrade'.
Have you got this option?
Sorry if I misunderstood your issue.
i do not see that tab anywhere... i appreciate the help, BTW. i just loaded the newest version of software also. I am either blind or it is not there...
found it. moron i is. thanks

Make sure to check the notes beside the patch, you will need to rescale your fan tables etc.
The COS just gives you the new boost table, to run SD you still need to make the changes to fail the MAF.
