Need some advice
I have a jb4 and am about to get an intake. One thing I am unclear about is weather I need to add a BOV and if do which one? Or does the diverter valve do the job? I have head it both ways and I am really confused.

How many miles are on your car? Generally a tune and just a intake won't need upgraded dv's right away. Anything over stock boost ill eventually wear the stock dv's out...but I didn't make a change until I went fbo and ran more boost.

The highest boost i've ran so far is ~15-16 psi on COBB S2 Aggressive. My Stock DVs seem to be doing just fine. We'll see what happens when I hit em with S2+
