I use my standard cab 5 speed 96 Dually to haul my race car trailer while loaded with a slide in camper (about 17K pounds loaded). It has 166K on it, I've replaced the head, clutch (10K RPM clutch) and done the dowel pin fix but I need more power while towing as it bogs way down on hills and has a hard time keeping at high way speeds all while the EGT creeps up. I've been looking at the kits from Banks Engineering as they claim to remedy the power, torque and produce good MPG. Has anyone used them or have other suggestions. I don't want to do major surgery and would like to keep it as simple as possible. I plan to keep the truck another 5 years and 80K miles (or more). Thanks,
