I am about to have installed my second JB4, on my new Alfa Romeo QV. I did a resonator delete and replaced it with an X-Pipe. Sometimes, it get too loud in D or Race mode. It would be awesome if the geniuses who work on the app would create a function or a map to have the exhaust valves closed in D mode. Then I would have the performance increase to the D mode without the super loud sound reserved for Race! Is this even possible?
