Mike/BPM have developed a great tune for the e9x M3 and the increased redline is a nice option with real world benefits. Steering and throttle calibrations are great options, too. GTS DCT update is the oem software all cars should have been delivered with from the factory. The complete package really does transform the car. Overall, I find the BPM stage 2 tune outperforms the Evolve stage 2 tune.
