This device works amazingly good. I never got an error code and my engine runs on 8 cylinders all the time. I have noticed better response on stand still take-off acceleration. I see a little improvement on the idle, but will probably improve more with changing the spark plugs and wires. It was incredibly easy to install, literally in seconds.
