Have been using VMSpc for a few years on our DSDP. Just put a Banks PowerPack on the Cummins ISC 350. I changed the setup to the ISC Banks one and found that my Banks boost gauge shows about 32-34 psi boost while the VMSpc never went over 24.3 psi. According to Banks I should see in the low 30's for boost now and that jibes with the gauge. I know I have the ISC w/Banks settings as the HP and torque show the new higher output. Is there something I need to change to get the correct boost reading?
