6.5/10 (Good value for experienced DIYers, risky for daily drivers)
For those who measure performance in seconds, a K99-tuned X5 M50i or M850i can drastically improve quarter-mile times. While a stock X5 M50i might run the quarter-mile in roughly 12.5 to 12.9 seconds, a K99-tuned version can dip into the high 11-second range, shocking sports car owners at the drag strip. k99 tuning
