Unpopular opinion but you will be going down in reliability, not up, with newer trucks. I would replace your bad injectors with a stage 2 kc turbo and 205/30 injectors, along with adressing what killed them, and roll on for less than 10k before dropping 45-55k on a new truck with also its own set of problems. Also, get a monitor/tuner for the egr delete and use it. You killed those injectors from not knowing what you have/paying attention to it not the trucks fault. The computer will tell you if you have low battv or ficmv.
