I'm going to get some high-temp vacuum line, catch can and JB4 next to install.
My idea is that with the JB4 I just reset the warning when it happens so I don't need to cycle the truck off and on ...
Outside of a possible turbo issue I'm not sure what causes mine.

How easy is it to reset the warning with the JB4? Are the controls mapped to the steering wheel or something?
