About the reliability issues...I wouldn't touch an n54 without bmw warranty....but up to you...
The only problem with the warranty is that if your running mods the warranty is pretty much useless, yes you can take the JB4 off before taking it to BMW but uninstalling downpipes is another issue. On top that if the turbos go in my 335i the last people I want touching my car is my local BMW dealer, who are not even competent enough to install the Apine speaker kit. I much rather take money to someone like Darrenwoods than deal with BMW directly....Can you tell i'm just a tiny bit dissappinted by my experiences of my local BMW dealers ??

Oh there is nothing 'airy' but the throttle response in my car with JB4, it's a fab mod just go for it!!
