Enjoying the resonse of the JB4 still. I will keep it in there until I go either Cobb or Dinan with ECU tuning if either of those is ever released.
Questions for other JB4 users:
Do you think Map 5 is better than Map 1?
Have you been able to run the USB cable into the glove box easily? I have not found the easy way into the interior that is posted over on N54tech for a 2011. Do I need to open up the ECU to find that hole?
