It doesn't add power on the dyno but it makes the car quicker accelerating. The stock TCM tune pulls timing clear back to zero degrees on the shift and closes the throttle. Then there is a recovery rate where it's added back. A good TCM tune will drop 1/4 mile times 2-3 tenths and even upwards of 4 tenths if you remove all Torque Management and Torque reduction.
