I see JB+ modules for sale awfully frequently. Why is everyone selling them? Is it because they don't work? Is it because they are just super easy to pull off to sell? Is it because people are getting chip tunes?

 

The JB+ is a nice little stop-gap to a full tune. I wasn't sure if I wanted to go for the full tune, so I added a JB+ that was purchased used off the forums. As soon as I realized I wanted more, I went for the full tune and sold my JB+.

Also, if the car is on lease, the JB+ is an easy way to add power without being detected by the dealer. Need service? Pull it out. Turning the car in at lease end? Pull it and sell it.

 

This, just about everyone I know who got a JB+ had it on for no more than a year and went for an actual flash tune.
