Please be aware that if someone digs deep enough (not the regular dealer, but say if your engine is blown and BMW challenges the warranty claim and decides to investigate) the higher HP and ft lb peaks do leave a trace. Does not depend on which tune you use.

But I figure this is old news.

For everyone that does not want any physical trace, or in general, I do recommend a proper ECU flash tune. Matched to the car, highest gains, can be combined with a speed limiter removal and a cat delete.
