I have a Scan Gauge with the MINI software.

At idle it's showing a negative number, is it normal? If it's normal, what numbers should I be seeing for this vacuum?

I can't drive right now so I can't tell if it'll display positive boost.

Thanks.

 

That's normal.

 

I had a problem with the bouquet due to a malfunctioning radiator. An intercooler has two main functions of lowering the temperature of the incoming air and decreasing the boost pressure. The pressure is reduced by the flow resistance of the intercooler. This, in turn, causes some limitations in the design, since a pressure drop of more than 1-2 psi is unacceptable. The pressure did not decrease, which caused the loss of boost, I looked options for 5.9 Cummins Intercooler Upgrade for my Dodge Banks 25980 Techni-Cooler Intercooler System is good radiator for my car
