View Full Version : Do ECU tunes make the car run quieter?

Ok....maybe I am hearing things...or not hearing things in this case, but in switching between stock and tuned modes, I feel like the stock mode produces more exhaust sound early on (at lower rpm) when on the throttle.

Could it be that with the flash the wastegate is being held closed longer to create more boost so that there is, in fact, less exhaust gas being spent at lower rpms when you are on throttle ???

Has anyone else experienced this, or is it all in my head? Stock exhaust, BTW.

Mine sounds louder with the extra HP, but I have the AWE exhaust. I'm currently flashed back to stock for service next week and it's definitely quieter than tuned, althought not a huge difference.
