I've had my BB for about 8 yrs so my controls may be different than yours. I've used it with a Grand Cherokee, Saturn LW300 and now the Liberty. I set the pressure at around 62. My sensitivity control doesn't have numbers just a "-" at 9 o'clock and "+" at 3 o'clock. I have it at the 11 o'clock position.
Hope this helps
