Questions...

I am a newbie here and enjoying the first couple weeks of my 335i... that being said I take interest in the above statement. What evidence is there that the JB4 has been causing any issues? Are there records of blown motors from JB4 installs? I am really interested in purchasing one, but am also scared of long-term reliability.

From what i've read so far everyone likes to do ECU's first; obviously because of bang for the buck. If we were to go the "safer" route is it safe to assume that I am better off upgrading intercooler, intake, DP's and exhaust before doing a tune? Wouldn't this create a "safer" environment for a tune?

Once again forgive me if I am totally off, but I am a newbie and just want to understand this completely before making a decision.
