Even if you do not want any more power, adding an intercooler will be good for the longevity of the motor if you want to track the car. Heat that is severe enough to drop power to stock levels is obviously not good. Contact ESS about an intercooler kit with your existing tune if you want. You may have to change to a slightly smaller pulley to overcome the restriction of the intercooler or it may be that the cooler and denser air leaves you with the same power. ESS would know. You would not be the first M3 owner to add an intercooler just to maintain consistent track performance -- this started years ago with the E36 M3 and continued with the E46 M3.
