If so what are you using, how does it pull, what would you change if you could

thanks

98 Newmar Mountainaire 40 feet 8.3 cummins 12 valve. Twin Turboed Hot rod P pump. Pulls like mad. Easily does 80 on flat and will climb at 55 with little effort. Make sure you have good brakes. EGT and boost gauges are critical as the coach was pushing 1600 degrees sustained before the added air flow. Now it rarely exceeds 1250.
