I would just leave it alone.

If you do change back to stock, you will throw a p1000 code and the testers will see that and tell you to get your problem fixed and retest.
What you really have to do to get rid of the code is do a "drive cycle" procedure to get rid of the p1000 code. That all depends on how much you drive it and how you drive it. That drive cycle procedure could take a week or even a month for an average driver.
Lots of others have passed with custom tunes and you should too.
Just remember to take the gryphon off the dash and cord out of the port.
Check the fuse for the cigarette lighter before and after testing also. This fuse powers the obdII port also.
