Wow...this is just laughable. I TOLD my service advisor I had the CEL deleter and he said "oh cool".And that was that.
The CEL deleter ONLY keeps the annoying "Increased emission" CEL from coming on. Everything else still comes on normally. Also, there are no stored codes for increased emissions with the CEL deleter. I've set of the code for brakes after running a dyno and it comes on normally.
