I was throwing codes all the time before my tune. With the exhaust mods, this is not uncommon. My tuner removed the inputs for the rear sensors (UpRev). While they still work and will send the voltage signal that adjusts the afr when the engine is cold, their voltage signal is blocked from the ecu. So, they always "look" ok even when they operate outside their voltage range. Best of both worlds.
