rite i have a 6n with a g40, its a very loud car, was decat, but had a cat put back in as the area i live in is tight on noise, and didnt really want to get caught without a cat. it made it slightly quieter but not much, anyway since ive had the car its been super loud on idle, like you have to shout to people to hear you lol, most other loud cars are quiet on idle and loud when moving, so whys mine constantly loud, it idles at just under 10 revs and often abit over, i have a remap chip on the way which requires ignition timing setup, will this shut it up abit or not at all, sorry for the stupid post but its just bugging me abit. cheers
