Ryboy do yourself a favor and chit chat with a tech at your local service dept and get there opinion on your SES light !
I have cat delete also and my SES is not disabled...
I spoke to a tech and was told Disabling the SES disables your CEL !!!
Not stirring shit just looking out for you , I would want the same if I was on the other side of the fence ..
::cheers:::
Better yet ask them when you get cat delete with their Dinan software does it disable the SES light ..
Then ask them what results will you encounter if a SES was disabled ...
