During the summer I have to pull 2-3 degrees at the 2-4K RPM because its so hot here but that's it. With a Dyno run it would be no different if I had a tune written any other time of the year vs the summer I would need to pull some timing anyways.
To be honest im not sure about right when it was tuned till now. I have owned the car about 4 months now and it has always done it since i have had it.
Sorry for late reply but i returned it to stock and now there is ZERO detonation. So it is the tunes for sure.
