E46 M3 tuned, standard exhaust and intake. Mild tune, overall power increase 9%. Please note a dyno is a tuning tool. We measure wheel power as it is a chassis dynometer, the calculation to measure engine power varies from car to car. The only accurate way to measure flywheel power is with an engine dyno. If we take the 9% increase in power convert that to manufactures rated power it equals to a power increase of 252kw to 274kw and 365nm to 398kw. Thm3 beforem3 afteris give us more power then the e46 M3 csl
