Advance IMO is only suitable for those with 335is or 1Ms running a piggyback. Heck, the stock curve in itself is already a touch too aggressive meth or not. Brings us back to the point regarding consistency.
Not for nothing, all this CPS offset or advance is nonsense if the car flatlines on its face after a shift.... Can't beat ignition safer than -1.88 degrees post shift.
