gotta do some logging to see what changes may be needed for the CAI.

Are you saying we should be looking at the long term fuel trims and adjusting accordingly?? If so do we adjust the injector slope. On one of my old tuners we adjusted fueling by remaping the MAF sensor tables?

correct ^ ^ ^

and on GM's, there is no changing the MAF sensor tables with the tool itself... that would need to be done in a custom tune
