My car is only in boost while I am on the throttle. I have had two supercharged cars, and everytime I am crusing, or not on the throttle at all, my gauge goes to or below the zero mark.

On the issue of not getting full boost, or losing boost; I am sorry guys, but I have not had this issue so I can not offer any advice.

 

yeah is what im seeing now...only when you're mashing the gas is when i see boost otherwise its on zero or below.
