So now that I have the new exhaust and tune in my car I noticed something strange.<p>Now when my car's in comfort or sport, when I come to a stop, the exhaust will have a burble at idle for a few seconds then it silences up, pretty much silent at idle after that point.<p>If sitting idling, I press the advanced button the burble comes back immediately. Push sport or comfort and it goes away within a few seconds.<p>I was under the impression that advanced only changes throttle mapping, nothing else with the ecu.....<p>Ok guru's what gives?

Mine does the same things, it even reads less vacuum when idling in advanced and much louder idle.

Timing (ignition) is different in Advanced when there is no load on the engine (idling etc). Because of this there is more torque during idling in advanced.<br>(perhaps better spooling up of turbo after shifting?)
