Kelleners Sport was the first, and perhaps only tuning company to currently have an engine tune to increase the N20 4 cylinder turbo engine power. Currently their power module is available for the N20 powered X3 and Z4 but their F30 power module is coming soon, very soon.
The Kelleners Sport power module increases the N20 horsepower from 245 stock to 294 and cranks up the torque from 260 to a road ripping 310 ft-lbs, with no additional parts needed! The F30 N20 power module for the 2012 328i is about 4 weeks away according to my source at Kelleners. We'll be following along on the progress of the power module as we're not going to be leaving the F30Driver Project 328i stock for long :excited:
