Please select the Select Pictures / Video Tab to obtain the Performance numbers for your specific vehicle. You will need to contact Dinan to get the specific Engine Chip for your car.
Dinan Performance Engine Chips unleash more power by re-programming the fuel mixture and ignition timing parameters of the engine management system. Furthermore the software safely raises the rev-limit, giving your BMW a broader power band and greater road speed potential in each gear. Significant gains are also achieved at part throttle, making extra power available where you spend the bulk of the time driving.
