The power that's delivered is a lot more controlled and smoother now, not as choppy and inconsistent compared to a stock tune. Definitely worth it to take it to Mike, to have him perform all his software updates and load up your vehicle with his tune. He's clearly a very busy person and for good reason, cause he produces results...
That is all.
Are you the owner of the white E90 or black E92?
