Sorry, but your tuner is wrong.
The 6 BTM....IS for tuning your car when it is running forced induction.
It....IS for spark timing control and that model (6 BTM) also increases your spark power.
It is a combination 6A and BTM box all in one.
It is used to ****** your ignition timing (1 to 3 degrees per PSI) as your boost level climbs to prevent the engine from detonating and self destructing.
Make sure the SCT chip has a setting to ****** the timing if you are boosted, otherwise your engine won't last very long.
