Ok, so as the title indicates I currently have these codes on truck. Bad front bank nox sensor and the dealership says my rear bank nox sensor module is bad. I've decided to delete the truck, mm3 lite kit on order.

With that said, has anyone else on here experienced this and how long do you think I can get away with driving the truck before it goes into limp mode? I plan on at least deleting the exhaust as soon as it gets to me but I need to haul my toy hauler in a week regardless, is this an option or am I asking for trouble?
