I have a Cummins ISL9 in a western star truck. It didn't come with a boost gauge so I want to install one. Anyone know about how much boost this thing would make max? I want to make sure I get a gauge that goes high enough.
Get a 60...my 5.9 liter dodge cummins will hit 35 psi so I'd think a 9 liter would be the same...
