I see you have it backwards again! A lean condition is what causes detonation. Always start out rich to protect an engine. More boost leans the mixture so you have to add more fuel as the boost increases. In the old Cummins engines the fuel was increased with an Android valve as the boost increased. Of course with a diesel engine they never detonate, they just get better economy when they run lean. In modern gas engines the fuel mixture is set rich like maybe 12 to one, then the oxygen sensor leans out the mixture so even if the oxygen sensor fails the engine will just run a little rich and won't be destroyed. Those big engines might need to be backed off to 5 degrees or even 0 degrees at start up. On my Toyota pickup, the timing is set at 0 degrees. First time I have seen that but that's what the book says.
