I believe it does. When my tune is installed I am running about 42 degrees of timing. Surprisingly no knock. Wouldn't recommend that much timing tho.

Yes, there is some timing added in the Performance tunes.

You must be seeing that at part throttle...WOT timing should be in the 22-25* range generally.
