There are still "flat" spots as I would call them throughout the rev band, but significantly better than without the tune.

If you have the N52 get a 3 stage intake, performance exhaust, and AA tune. I don't need a dyno prove there is more power. Car now easily steers with throttle modulation in 2nd gear, 3rd gear pulls much harder all the way up. Wonderful be back in my330i again, sans the larger brakes.
