Timing map with 280 cams...
Couple things.
Many have neglected to notice you are running BC 280's, not HKS, GSC or Compcams.
They have different lift and actual duration than the rest of the cams.
No one should be able to directly compare their ignition timing map unless they are running the BC 280 cams.
Furthermore, without offense intended. Your timing map is garbage. 10* from 5500+? That is too much, too early.
Spark plugs heat range, cam gear degreeing, valvetrain status should also be taken into account.
