Per my tuner,
On an L99 car with a power adder, bolt on's and torque converter, your supposed to use the PADDLE shifter's when going down the dragstrip.
They are adaptive and will lose all that lag they come with from the factory over time.
Also by removing 110 lbs of weight from the car, and 36 lbs of rotational weight from the front wheels and driveshaft, you shouldn't get ANY GAIN whatsoever in your ET.
HP tuners here I come.
