Just got the dash boss an noticed that when I floor the truck the boost only goes to 22.2 then goes to 0 an when I let off it goes back to working normal would anyone know why that is?

 

No idea but probably something simple. Maybe call Ken at Dashboss. He is very good about supporting customers with any issues that may arise. If you have to leave a message, he will be quick to return your call, though he usually is available to answer in my experience. Great customer service!

Ken's number is 801-917-4101

 

Also try one of the other boost gauges. One is MAP reference, one is PCM reference and another is LOW PSI resolution calibrated.
