This kit is way worse at the track actually because with the lack of a heat exchanger. When the motor/engine bay heats up at the track, the tune will have to pull timing. At a certain point, it pulls so much timing that it is likely no faster than a bolt-on NA M3. So after say lap 3, you lost 100 HP yet still have the 50 pounds added to teh front of the car. A dedicated water/meth injection system could restore the lost ~ 100 HP however.
