After our manifold change and Banks waste gate repair, plus getting the Banks module working again , Our 8.3 cummins now produces 32 pounds of boost pressure at 825 degrees. It required 1100 degrees EGT to produce 28 pounds of pressure prior to the repair. a 25 mile test drive showed 9.5 miles Per gallon on the road tex computer in the coach.
I had the same system got as much as 38lbs boost.350ISC engine had decent power after the banks egt would go to 1200
