Is there some kind of a adjustment within the little black control unit

You have to install the JB software on a laptop and physically connect to the black box and tweak the PSI over stock field to 3 or 4 or 5. Haven't done so yet but plan on it this weekend. Will let you know how it goes. Plus 4 PSI should be ok AFAIK but over that you might see some codes. Will report back ASAP
