I plan to almost immediatley buy the JB2. Seems like a no brainer. $250 for 50hp.

As I understand, its plug and play in about 5 mins, and throws no codes etc.

Is that correct?

I could go for the JB4, but the wiring harness seems more elaborate and complicated to put in and take out on short notice. Not to mention, I am not sure I want to turn up the boost THAT much and compromise the reliability warranty, etc.
