No, at least in my case. My car is having the same VBox times running both 241e and tune. Compared to stock '13 decat no tune as well.

And what is the problem exactly? As far as I know, secondaries only check that cats are still in place and still efficient. A friend of mine has been driving the car ('13 no tune mentioned above, secondary o2s removed entirely) since last summer with no issues except the CEL. Yet he is 0.1s faster than any other local m3.

Did he also mention what wear it causes exactly? The burble itself is just fuel firing in the exhaust. You can't hear anything unless it's (exhaust) warmed up.
