They might have had three cars blow up on their dyno but there are a lot of variables and unforseen circumstances as well.

or
MBT (minimum best timing). Advancing the timing further increases the chance of knock and also increases vehicles emissions of hydrocarbons and NOx.

Maximum Brake Torque. The optimum spark timing that gives the maximum brake torque. In a very small nutshell when no more power can be gained by advancing the timing throughout the ignition tables. Once you find MBT on a motor rule of thumb is to take a couple degrees out of the corresponding ignition tables.
