Mike brought his 328i to us after he was having some driveability issues that he wanted us to clear up. After looking over his 328 that was fitted with an Active Autowerke C30 Rotrex supercharger kit we found a couple minor issues that was causing his loss of power. After making some adjustments and replacing his air filter, mike was able to put down over 270Rwhp! The initial dyno when he brought the car into us was varying from 230-240rwhp. The Active Autowerke kits are quite amazing and the R&D put behind the kit truely shows in its performance. If you would like any information on Active Autowerke performance products or have a car with Active parts installed, we are an Active distributor and can service these kits as needed. Please feel free to contact us for any additional information!
