I just threw the question up over on n54tech to see what they'll say. My question is if my current (non-adjustable) wired-in DP fix will work w/the JB4 or if I, too, will need the new adjustable one. I now understand the reason for needing the additional fix. Also, I can't remember if I mapped mine off for my last inspection. If I didn't, then nothing was detected b/c I passed.
So, the answer for if you "need" the additional DP fix seems to be yes, in order to map off the tune but still have coverage for the missing cats. I guess it all goes back to what state you're in and how they inspect the cars. Mine just plugged up to the OBD and kept going. Should be interesting to see what happens the next time, since I've had my mufflers deleted. (??)
