Ok I have a 2017 6.7 with a g56 3.73 gears and 35s. It weighs 12000lbs and I frequently pull a 15k fifth wheel. I have already fully deleted, put in a dual disc south bend, had the head trued installed a fleece coolant bypass and arp 625s. Now it's time for fueling and turbo. I plan to add a lift pump and 2nd gen swap next and a small set of injectors afterwards. I've been looking at the s467 kits and have read alot of mixed reviews also have been looking at the s369sxe. I need some feedback from some people with similar setups. I want it to tow well and not give me any problems. Who can help me out?
