I posted a while back that I had dynoed my car and it was detonating. I plan on going back this Saturday but I will have an AFC, EGR block plates, and be running 100+ octane - so hopefully no more detonation. My question is, what else would cause the detonation. What else could I check or replace to ensure that my car will not detonate?

Hot charge air
Too much boost
Too much compression
Sharp edges in the combustion chamber
Oil in the charge air
Hot coolant
Excessive exhaust backpressure
Too much timing advance
Low quality fuel
Not enough fuel
Spark plugs that are too "hot"
